Current behavior
Hello,
I'm using the graphql example( in the example directory of nest) with the Cat CRUD and i try to use a union type and interface but i didn't find a way to do it.
When i try to request my data with a fragment, i have the following error :
"Abstract type MutationResult must resolve to an Object type at runtime for field Mutation.createCat with value "[object Object]", received "undefined". Either the MutationResult type should provide a "resolveType" function or each possible types should provide an "isTypeOf" function."
There is nothing in the doc explaining how to use union / interface, and there is nothing in the graphql example.
In the apollo documentation, the type resolver ( here "Cat" Resolver") should implement a __resolveType function. I tried to set this function in the @resolver('Cat') class CatsResolvers
but it's not working.
I tried to add it on the cat resolvers class
Expected behavior
The request should return either a Cat item or GraphQLErrorItem from my schema definition.
Minimal reproduction of the problem with instructions
export interface GraphQLError {
readonly message: string;
readonly errorCode: number;
readonly type: string;
}
type GraphQLError {
message: String
errorCode: Int
type: String
}
union MutationResult = Cat | GraphQLError
- change the createCat Mutation in the schema
- createCat(name: String, age: Int): MutationResult
- add the function in cats.resolvers.ts in the CatsResolvers class
__resolveType(obj, context, info): string{
return obj.errorCode ? 'GraphQLError' : 'Cat';
}
What is the motivation / use case for changing the behavior?
Environment
Nest version: 4.5.10 (core)
For Tooling issues:
- Node version: 9.4
- Platform: Mac
Others:
Since apollo-server-express
is not working in the Nest way, a new middleware, that adapts to the Exception handling of Nest should be created. The original issue was created in @nestjs/nest
since the example in the documentation leads to use this library.
Related issue nestjs/nest#556
I have seen those similar issues nestjs/nest#484, nestjs/nest#488 and they seem to be resolved. However, I am on @nestjs/graphql v3.0.0, @nestjs/common and /core v5.0.0 and the following code:
@Module({
imports: [GraphQLModule]
})
export class GraphQLSetupModule {
private readonly schema: any;
constructor(graphQLFactory: GraphQLFactory) {
this.schema = graphQLFactory.createSchema({
typeDefs: mergedTypes
});
}
}
where mergedTypes
is exactly:
schema {
query: Query
}
type Query {
countries: [Country]
}
directive @entity on OBJECT
type Country @entity {
# The id is also the official ISO code of the country.
_id: ID
name: String
}

typePaths

Very excited about NestJS. Thinking of becoming a sponsor if it proves out for my new project.
I need to get GraphQL subscriptions working. For starters, I've implemented the example from docs, and now I'm trying to connect GraphiQL with something like this:
consumer
.apply(graphiqlExpress({
endpointURL: "/graphql",
subscriptionsEndpoint: `ws://localhost:${process.env.PORT || 3000}/subscriptions`
}))
.forRoutes({path: "/graphiql", method: RequestMethod.GET})
.apply(graphqlExpress(req => ({schema, rootValue: req})))
.forRoutes({path: "/graphql", method: RequestMethod.ALL});
I'm getting ERR_CONNECTION_REFUSED
in browser console. I feel like I'm missing the connection between GraphQL Subscriptions and WebSockets, but I can't seem to piece it together from the docs.
Are there any working e2e examples out there?
If the parent resolver and the child resolver both have Guard, the validate function of the guard will be triggered twice. The guard of parent will be passed with the request object, while the guard of the child will be passed with whatever parent resolver returns.
@Resolver('User')
export class UserResolvers {
constructor(
private readonly userService: UserService
) {}
@UseGuards(CustomGuard) // validate function here will get request object
@Query('me')
async getUser(obj, args, context, info) {
const { user } = context
return {
account_type: user.accountType,
balance: user.balance,
currency: user.currency,
id: user.accountId
}
}
@UseGuards(CustomGuard) // validate function here will get the result of getUser
@ResolveProperty('balance')
async getBalance(obj, args, context, info) {
if (obj.balance) return obj.balance
const data = await this.userService.getAccount(context, context.user.session)
return data.balance
}
}
Does anybody know how to solve this problem?
I have a question; I have the following scheme:
scalar qq
type Liquid {
nliquid: Int
fecha: qq
}
type Query {
liquidaciones: [Liquid]
}
why when sending the query
{
liquidaciones{
nliquid
fecha
}
}
get the next result
{
"data": {
"liquidaciones": [
{
"nliquid": 1,
"fecha": "2004-11-16T03:00:00.000Z",
},
{
"nliquid": 2,
"fecha": "2004-12-13T03:00:00.000Z",
"descrip": "NOVIEMBRE 2004"
}
}
without having defined the scalar qq, even changing qq for any other text (other than Int, String, Float or ID)
This syntax is not working in the NPM version. Probably a release is pending.
const resolvers = {

Current behavior
Using Nestjs with the GraphQLModule as documentation describes, there are a problem with throwing HttpException. The error message that GraphQL returns, contains "[Object Object"] in the message field instead the HttpException message.
The GraphQL.js library is expecting an Error instance, but HttpException not inherit from Error. What is the main reason for HttpException is not extending from Error?
In addition to this any Exception Filter is not working.
Expected behavior
Proper error handling and Exception Filters working with GraphQL.
Minimal reproduction of the problem with instructions
Install @nestjs/graphql and configure it as documentation describes. In any resolver try to throw a HttpException (or a inherited custom one). GraphQL returns an error like this:
{
"data": {
"findOneUserById": null
},
"errors": [
{
"message": "[object Object]",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"findOneUserById"
]
}
]
}
What is the motivation / use case for changing the behavior?
Proper error handling working with GraphQL and documentation for how to deal with this.

Current behavior
In the interface GqlModuleOptions
, the typeDefs
property is inherited from the apollo-server Config
interface, which defines it as typeDefs?: DocumentNode | Array<DocumentNode>;
However, when I pass a DocumentNode as the value of typeDefs
, I get the following error:

Passing a string representation of the schema on the other hand works, but then I need to cast the string to any
to avoid type errors.
This line in the GraphQLFactory
class seems to be the point that the value is used as a string (or array of strings to be exact):
|
typeDefs: gql` |
|
${options.typeDefs} |
|
`, |
Expected behavior
Either the GraphQLFactory should perform a check to see if the typeDefs
is a DocumentNode, and if so then skip the gql
tag call.
Or just change the GqlModuleOptions
to make typeDefs a string type.
Environment
Nest version: 5.3.0, graphql v5.1.0
Ho can the query method be passed to the right Query type parent?
Or how can the resolver class be annotated correctly in order to resolve?
.graphql
type CustomQuery{
foo: String
}
type Query {
mw: CustomQuery
}
CustomResolver
import { Query, Resolver } from '@nestjs/graphql';
@Resolver()
export class CustomResolver {
constructor() {}

Hi,
I have an issue, when merge types and create schema, on terminal console show errors like this:
node:8726) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): TypeError: buildASTSchema.getDescription is not a function
(node:8726) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled willterminate the Node.js process with a non-zero exit code.
this is my code
const typeDefs = this.graphQLFactory.mergeTypesByPaths('./**/*.graphql');
const schema = this.graphQLFactory.createSchema({ typeDefs });
consumer
.apply(graphqlExpress(req => ({ schema: {}, rootValue: req })))
.forRoutes({ path: '/graphql', method: RequestMethod.ALL });
In @query, we get the parameters (args, context, info) like this
@Query()
user(_, args, context, info) {
And req can be retrieved from context or info
Is it possible to get the req from @ResolveProperty too? I have tried something like this but it does not work.
@ResolveProperty()
userExperience(user: user, @Req() request) {
I using fastify in nestjs as default, but i can not using this package. How should I do it?
Example:
`import { Query, Resolver } from '@nestjs/graphql';
@resolver('Example')
export class ExampleResolvers {
constructor() {
}
@query('example')
async example(obj, args, context, info) {
return {name: 'alik'};
}
async otherMethod() {
return 'hello word';
}
}
`
y have this error (node:8600) UnhandledPromiseRejectionWarning: Error: Example.otherMethod defined in resolvers, but not in schema

Current behavior
I can't access the request within my guards anymore. The request within the execution context is always undefined. It looks like the request doesn't get passed through apollo server correctly.
Expected behavior
The request should be accessible within guards.

Environment
Nest version: 5.3.0
This error accurs since apollo server was updated

I have the following code snippet that works fine in graphql-yoga.
Subscription: {
post: {
subscribe: (parent, args, ctx, info) => {
return ctx.db.subscription.post(
{
where: {
mutation_in: ["CREATED", "UPDATED"]
}
},
info
);
}
}
},
If I try to get the context in the Nest way - all of those args are undefined
@Subscription('post')
onPostMutation(parent, args, ctx, info) {
// all args are undefined
// ...
}
So my question - how to get context and args for a subscription?
I'm submitting a...
Current behavior
(Me again! Thanks for the incredibly rapid response to my last two issues - hopefully this is the last for a while ... 😄 )
So in my app I am using the typeDefs
config option and omitting typePaths
because I do some of my own pre-processing of the schema files before handing them off to Nest.
There is an issue currently with this part of the GraphQLModule
code:
|
const typeDefs = this.graphQLFactory.mergeTypesByPaths( |
|
...(this.options.typePaths || []), |
|
); |
|
const apolloOptions = await this.graphQLFactory.mergeOptions({ |
|
...this.options, |
|
typeDefs: extend(typeDefs, this.options.typeDefs), |
|
}); |
When this.options.typePaths
is falsy (undefined in my case), then the call to this.graphQLFactory.mergeTypesByPath()
will return the following string:
When this is later combined with the string I pass as the typeDefs
value, then the resulting schema only contains my Queries, but none of my Mutations.
Expected behavior
Passing typeDefs
and no typePaths
should result in a schema exactly equivalent to that defined by the typeDefs
string.
Minimal reproduction of the problem with instructions
git clone [email protected]:nestjs/nest.git
cd nest/sample/12-graphql-apollo
npm install
- edit app.module.ts to look like:
GraphQLModule.forRootAsync({
useFactory() {
return {
installSubscriptionHandlers: true,
typeDefs: `
type Query {
getCats: [Cat]
cat(id: ID!): Cat
}
type Mutation {
createCat(name: String): Cat
}
type Subscription {
catCreated: Cat
}
type Cat {
id: Int
name: String
age: Int
}
`
};
},
}),
npm run start
When trying to execute the createCat
mutation, you will not get the error: "Schema is not configured for mutations."
Additional note: I noticed when putting together the reproduction that when passing the above config to the .forRoot()
method, the app does not even bootstrap, instead failing with the error:
UnhandledPromiseRejectionWarning: Error: Type "Query" was defined more than once.
at Object.buildASTSchema (C:\Development\temp\nest\sample\12-graphql-apollo\node_modules\graphql\utilities
What is the motivation / use case for changing the behavior?
Sometimes you need to pre-process the typedefs before handing off to Nest. In my case, I use user config to create custom fields at run-time.
Suggested fix
I fixed the issue locally by changing line 100 to:
const typeDefs = this.options.typePaths ? this.graphQLFactory.mergeTypesByPaths(
...(this.options.typePaths || []),
) : '';
Environment
Nest version: 5.3.2, graphql v5.1.1
Is there any way to add @Body to this library for the args param. Finding it frustrating having to convert POJO's from inputs to TypeScript classes.
