I'm trying to use the GraphQLGatewayModule module from @nestjs/graphql.
To test, i'm using an GraphQL API free: https://anilist.co/graphiql
But i always get HTTP 400 status.
My code:
import { Module } from '@nestjs/common';
import { GraphQLGatewayModule } from '@nestjs/graphql';
@Module({
imports: [
GraphQLGatewayModule.forRoot({
server: {
// ... Apollo server options
debug: true,
cors: true
},
gateway: {
debug: true,
serviceList: [{ name: 'TEST_GRAPHQL_GATEWAY', url: 'http://user-service:3000/graphql' }],
}
})
]
})
export class AppModule { }
I always get HTTP 400 status. But this api it's ok. I get this message:
Encountered error when loading TEST_GRAPHQL_GATEWAY at http://user-service:3000/graphql: 400: Bad Request
[INFO] Fri Mar 20 2020 17:52:20 GMT+0000 (Coordinated Universal Time) apollo-gateway: Gateway successfully loaded schema.

Am I using GraphQLGatewayModule in the wrong way?
Thanks!
