Graphql-code-generator: Fails to load schema (worked before update)

[nebbles]

Describe the bug

Fails to correctly resolve a field that is defined in another file.

$ graphql-codegen --config codegen.yml
  ✔ Parse configuration
  ❯ Generate outputs
    ❯ Generate ./src/schemaTypes.d.ts
      ✖ Load GraphQL schemas
        → Failed to load schema
        Load GraphQL documents
        Generate


 Found 1 error

  ✖ ./src/schemaTypes.d.ts
    Failed to load schema from schemas/*.graphql:

        Field user: Couldn't find type User in any of the schemas.
        Error: Field user: Couldn't find type User in any of the schemas.

To Reproduce
Steps to reproduce the behaviour:

This one was a really hard one to reproduce. But I have now copied 'enough' of my repository to codesandbox such that it reproduces the issue.

NOTE I only started getting this error when upgrading from 1.11.2 to 1.12.1.

1. My GraphQL schema:

It's best seen in the Codesandbox

1. My GraphQL operations:

# Put your operations here

1. My codegen.yml config file:

overwrite: true
schema: "schemas/*.graphql"
documents: null
generates:
    ./src/schemaTypes.d.ts:
        plugins:
            - "typescript"
            - "typescript-resolvers"
            - "typescript-mongodb"

Expected behavior

For this to generate. It worked correctly on the slightly older version (1.11.2). I am therefore stuck on this slightly older version.

Environment:

My local dev environment (not Codesandbox)

• OS: macOS (although reproduced through Codesandbox - Linux)
• @graphql-codegen/...:
• NodeJS: 10.15.3

Additional context

@ardatan can you please take a look?

Same here, downgrading back to 1.8.3 worked for me.

[smykhailov]

Very strange error, I got the same and found the fix
instead of

    "@graphql-codegen/cli": "^1.11.2",
    "@graphql-codegen/introspection": "1.11.2",
    "@graphql-codegen/typescript": "1.11.2",
    "@graphql-codegen/typescript-mongodb": "1.11.2",
    "@graphql-codegen/typescript-resolvers": "1.11.2",

I changed the versions to:

    "@graphql-codegen/cli": "^1.11.2",
    "@graphql-codegen/introspection": "^1.11.2",
    "@graphql-codegen/typescript": "^1.11.2",
    "@graphql-codegen/typescript-mongodb": "^1.11.2",
    "@graphql-codegen/typescript-resolvers": "^1.11.2",

I didn't dig to root cause, but hope it will help in investigation

[dotansimha]

@smykhailov All you version should be either pinned or not, otherwise you risk in missmatch and duplicate packages.

[dotansimha]

@nebbles You are having the same issue as @smykhailov .
You need to pin, or align all your codegen dependencies. Either use ^version or just version, because otherwise you'll get a mixup of dependencies, and it will cause multiple versions of codegen core package.

I tested both solutions on your repo and it works. Also tested latest codegen version and it also works.

Closing.

If someone else is having this issue or similar - first, align you codegen versions is package.json :)

[nebbles]

Thanks @dotansimha! Not sure how they got out of sync with only one defining a ^version. Everything back and working 🙏

For those who were still having issues, my problem was that I changed the port my backend instance was running on so it couldn't find my /graphql endpoint. I fixed the URL and it got fixed.
