To avoid the N+1 problem， I defined a DataLoader, for example ReviewsDataLoader. After I do a mutation, I call the query method again. The "load" method in the ReviewsDataLoader is called multiple times. ReviewsDataLoader not work. I don't know how to solve this problem.

what is the best way to dump the I got as a response from the execution?

dgsQueryExecutor.execute but no matter what it returns a linked hash map, which therefore
lose the order when I try to convert it back to JSON with?

I have the impression there must be an obvious vai to dump the response... and I am looking for it :)

I am having a class Foo & Boo

public class Foo{
String a;
}
public class Boo extends Foo{
String b;
}

Boo will be my output object in .graphqls

I am able to get the response of Boo in this. But if I wanted to get the a also as the output of above query then how can we define the type and graphqls.

Is there any support present in dgs framework.

I added mysql to this repo here, and now DgsSchemaProvider is not finding my datafetcher DgsComponents.

Hi there.

I found issue when try to excute this project.

Using commit that 'spring boot 3.x' applied then not appear '/graphql' endpoint.

spring boot 3.0 ( commit ID : 20fb399 ) running console

spring boot 2.7 ( commit ID : c8e0bcb ) running console

How to solve this issue?

Thanks in advence.

If you change this line to

.reviews().submittedDate()

The ObjectMapper cannot deserialize the date.

Error deserializing data from '{"data":{"shows":[{"title":"mock title","reviews":[{"submittedDate":"2021-04-15T11:37:22.424887-04:00","username":"DGS User","starScore":5},{"submittedDate":"2021-04-15T11:37:22.424953-04:00","username":"DGS User 2","starScore":3}]}]}}' with JsonPath 'data.shows[*]' and target class java.util.List<com.example.demo.generated.types.Show>

Request failed when some value has the line break like \n in it.

It's a bug, or my code missing necessary escape porcess?

I tried escape the \n to \\n in json value. But ther sever side treated the \\n to \n as string instead of line breaker. It's server side's fault?

client.reactiveExecuteQuery(queryRequest.serialize())
client is a instance of [WebClientGraphQLClient]

WebClientGraphQLClient.class
@Suppress("BlockingMethodInNonBlockingContext") val serializedRequest = GraphQLClients.objectMapper.writeValueAsString( Request( query, variables, operationName ) )

I noticed some strange behavior I think in the the code above.

if the LF (\n) in json value, the result of serializedRequest is \n.
if the escaped LF (\n) in json value, the result of serializedRequest is \\n.

I expect result of serializedRequest is \n. (Since the server side can't parse the json which \n in it well, \n is OK.)
How can I do this? Can I customize the ObjectMapper above?

Is it possible to add a test case for uploading an artwork according to mutation "addArtwork(showId: Int!, upload: Upload!): [Image]!"?

Sorry if I'm wrong.
I noticed the method below it's seems like can not properly treat the block string (ex: description : """abc""" with triple ")
String com.netflix.graphql.dgs.client.codegen.GraphQLQueryRequest.serialize()

The value of string like ""abc"" will be treated as "\"\"abc\"\"" after serialize().

Any solution I can treat the block string properly with the DGS framework?

graphql/graphql-spec#327

Provide a basic integration with Spring Security that can be used to document how you can get the Authentication reference in a data fetcher .

We should have an example of using a custom directives for both Input and Output types.
