[wesselvdv]

Describe the bug
Providing .graphql file with correct schema gives Loading schema.graphql gives Query root type must be provided. error

To Reproduce
Steps to reproduce the behavior:

1. Use the following schema:

schema {
  query: QueryRoot
}

type QueryRoot {
  """Fetches an object given its ID"""
  node(
    """The ID of an object"""
    id: ID!
  ): Node
}

1. Use any document
2. Run the following command: gql-gen --watch --schema './src/app/graphql/schema.graphql' --template graphql-codegen-apollo-angular-template --out './src/app/graphql/queries.ts' './src/**/*.graphql'

Expected behavior
Expected schema to be loaded from .graphql file.

Environment:

• OS: alpine
• Codegen: 0.13.0
• Node: 10.11

I tried to reproduce it as you can see in #816 but it seems everything's fine.

Actually it doesn't work but I fixed that in f1e5a0c05d18da32564a55e14db20de89220a0a2

Fixed in 0.14.0 🎉

@dotansimha Using the example schema above still gives an error in 0.14.0:

Unable to find the schema root matching query

[furier]

Yeah @dotansimha, I also have the same problem in 0.14.1

$ gql-gen

Sorry for nagging you, but I am very eager to test out the graphql-codegen-apollo-angular plugin to start using it in our angular application. :D Is this still waiting-for-release ?

[dotansimha]

@kamilkisiela is working on fixing it right now :)
The issue is with the package that we are using for merging GraphQL schemas (@graphql-modules/epoxy).

@dotansimha Also seems this issue is not necessarily related to using graphql(s) files. I am also experiencing this when using the previously working .json file.

[kamilkisiela]

It's related to the way schemas are being merged, a schema definition object is removed and it only treats Query, Mutation and Subscription as root types.

Fixed in #899

[dotansimha]

@wesselvdv @furier Can you please try with 0.15.0-alpha.7c1a7d2a from npm? it includes the latest fixes that @kamilkisiela did .

[furier]

Have had meetings all day, but ill get right on it now. :)

[furier]

@dotansimha @kamilkisiela works like a charm when i upgraded all the packages to that version :)

[wesselvdv]

When will a new version be cut?

[dotansimha]

Fixed in 0.14.2 🎉
