Fixed in v0.5.1

The problem was that the apollo client adds some introspection to your query. This is what apollo was actually sending to the server:

{
  todos {
    task
    comments {
      title
      __typename
    }
    __typename
  }
}

The problem was that Join Monster tried to look for a user-defined __typename field. The internal fields for introspection should be ignored by Join Monster.

This is fixed. It should now work without modifying your code.

This is most likely a problem in Join Monster.

Can you post:

the actual GraphQL query that is getting received by the server?
your schema definition?

I want to try to reproduce this error. Also, if you have a public repo with the source code that I could check out, that would be great.

Todo:

const TodoType = new GraphQLObjectType({
    name: 'Todo',
    sqlTable: 'todos',
    uniqueKey: 'id',
    fields: () => ({
        id: {
            type: GraphQLInt,
        },
        task: {
            type: GraphQLString,
        },
        completed: {
            type: GraphQLBoolean,
        },
        comments: {
            type: new GraphQLList(CommentType),
            sqlJoin: (todoTable, commentTable) => `${todoTable}.id = ${commentTable}.todo_id`
        }
    })
});

Comment:

const CommentType = new GraphQLObjectType({
    name: 'Comment',
    sqlTable: 'comments',
    uniqueKey: 'id',
    fields: () => ({
        id: {
            type: GraphQLInt,
        },
        title: {
            type: GraphQLString,
        }
    })
});

Root:

const RootQuery = new GraphQLObjectType({
    name: 'Query',
    fields: () => ({
          todos: {
            type: new GraphQLList(TodoType),
            resolve: (parent, args, context, resolveInfo) => {
                return joinMonster(resolveInfo, context, sql => {
                    return knex.raw(sql);
                });
            }
        },
    })
});
