Graphql: Specified query type "Query" not found in document with none graphql file.

[dzzzzzy]

When I using the sample/12-graphql-apollo project, and I remove the graphql file, then run this project.

It throws some error:

(node:5278) UnhandledPromiseRejectionWarning: Error: Specified query type "Query" not found in document.

When console.log(typeDefs) with none graphql file at other projects, it always throw this error and console shows:

schema {
  query: Query
}

Could you provide a repository that reproduces your issue?

Same here:

Steps to reproduce:
in new nestjs project follow graphql quickstart:

1. npm i --save @nestjs/graphql apollo-server-express graphql-tools graphql
2. Import GraphQLModule to ApplicationModule
3. Start an application (prod / dev)
4. Observe an error.

I get the exact same error as well trying to follow the official tutorial at https://docs.nestjs.com/graphql/quick-start

[kamilmysliwiec]

Ensure to update @nestjs/graphql to latest version.

[davidlav]

I'm using version 5.2.2 of @nestjs/graphql and am still getting the same error as @antontemchenko by following the same four steps in the GraphQL quick start.

[kamilmysliwiec]

Just pushed 5.2.3 temporary fix. The issue comes from the underlying lib: https://github.com/okgrow/merge-graphql-schemas/issues/155

[davidlav]

Thanks! Appreciate the super fast fix. You've got a great framework here, really enjoying learning it!

[kamilmysliwiec]

Faced some issues with GraphQL playground. For better UX I encourage to update into 5.3.0

[davidlav]

Thanks! Was beating my head against the wall last night wondering why the playgound was having server connection errors.
