GraphQL Source API Erroring

[ddcollins]

Hello, I have a GraphQL source as such:

sources:
  - name: Academy
    transforms:
      - resolversComposition:
          compositions:
            - resolver: 'Query.*'
              composer: ./src/middleware/preview-authorization-header.js
      - namingConvention:
          typeNames: pascalCase
          # Causes issue with union types
          #enumValues: upperCase
          fieldNames: camelCase
    handler:
      graphql:
        endpoint: ${DIRECTUS_HOST}/graphql
        schemaHeaders:
          Authorization: Bearer ${DIRECTUS_API_TOKEN}
        operationHeaders:
          Authorization: "Bearer {context.directusAuthorizationToken}"
          Auth-Token: "{context.headers['x-auth-token']}"
          X-USER-ID: "{context.headers['x-user-id']}"
        batch: false

And in my code I am trying to call a query:

let result = await Academy.api.lessonById({id: itemId}, {
    selectionSet: `{ id }`
});

But getting this error:

GraphQLError [Object]: GraphQL schema validation error.
    at Object.relocatedError (/app/node_modules/@graphql-tools/utils/index.cjs.js:3960:12)

  path: [ 'lessonById' ],
  extensions: { code: 'INVALID_PAYLOAD', graphqlErrors: [ [Object] ] }
}

The query does indeed exist:

Am I doing something wrong here?

{
  "name": "mesh",
  "dependencies": {
    "@graphql-mesh/cli": "^0.29.12",
    "@graphql-mesh/config": "^0.17.0",
    "@graphql-mesh/graphql": "^0.17.7",
    "@graphql-mesh/json-schema": "^0.14.8",
    "@graphql-mesh/runtime": "^0.17.0",
    "@graphql-mesh/transform-naming-convention": "^0.6.48",
    "@graphql-mesh/transform-rename": "^0.8.18",
    "@graphql-mesh/transform-resolvers-composition": "^0.9.8",
    "dotenv": "^8.2.0",
    "graphql": "^15.5.*",
    "gravatar": "^1.8.1",
    "jsonwebtoken": "^8.5.1",
    "minimist": "^1.2.5",
    "node-fetch": "^2.6.1",
    "underscore": "^1.13.1"
  }
}

Update I dug into the GraphQL Errors object and see the Syntax Error: Unexpected <EOF>

[
  {
    message: 'GraphQL schema validation error.',
    extensions: { code: 'INVALID_PAYLOAD', graphqlErrors: [Array] }
  }
]
[
  {
    message: 'Syntax Error: Unexpected <EOF>.',
    locations: [ [Object] ]
  }
]

Update#2 Simplified to let result = await Academy.api.lessonById({id: itemId});

And now see errors:

[
  {
    message: 'GraphQL validation error.',
    extensions: { code: 'GRAPHQL_VALIDATION_EXCEPTION', graphqlErrors: [Array] }
  }
]
[
  { message: 'Unknown type "ID".', locations: [ [Object] ] },
  {
    message: 'Cannot query field "lesson_by_id" on type "Query".',
    locations: [ [Object] ]
  }
]

Suspect it's issue with transforms.

Would help probably to get the contents of preview-authorization-header.js and your schema. Hard to see anything glaring right now, I'd only be guessing at resolutions.

[ddcollins]

preview-authorization-header.js

/**
 * Sets the Directus Authorization token to either the preview or non-preview token.
 **/
module.exports = next => async (root, args, context, info) => {
    let client = context.headers['x-authorized-client'];

    if (client === process.env.ACADEMY_PREVIEW_CLIENT) {
        context.directusAuthorizationToken = process.env.DIRECTUS_PREVIEW_API_TOKEN;
    } else {
        context.directusAuthorizationToken = process.env.DIRECTUS_API_TOKEN;
    }

    return next(root, args, context, info);
};

I'll start digging into the internals of Mesh and try and figure out what the bug is. I'm pretty confident it is issues with the transforms and using the internal SDK, as I've run into a similar issue before and had to stop using a transform altogether. That's not going to be an option at this point however, as we have production mobile app and web apps using our GraphQL API already and I can't turn off the camel casing else all would break.
