TypeError: Cannot read properties of undefined (reading 'body')\n at getLocation

[igortas]

Hi,
I'm getting this error body undefined when I've tried working with this example:

https://the-guild.dev/graphql/codegen/docs/guides/graphql-server-apollo-yoga-with-server-preset

codegen.yml

schema: '**/schema.graphql'
generates:
  apps/api/src/schema:
    preset: '@eddeee888/gcg-typescript-resolver-files'
    watchPattern: '**/*.mappers.ts'

Resolver:

Experiencing this too, maybe we are following bad guides online:

codegen.ts:

import type { CodegenConfig } from "@graphql-codegen/cli";
import { defineConfig } from "@eddeee888/gcg-typescript-resolver-files";

const config: CodegenConfig = {
  schema: "./src/schema/**/schema.graphql",
  generates: {
    "src/schema": defineConfig(),
  },
};
export default config;

Hello, this usually happens because of validation issues in the schema. Could you share your schema?
If not (for privacy/security reasons), it's understandable but ,it could be a bit hard to debug

Hi, whilst these errors appear when there's an issue with the schema, TypeError: Cannot read properties of undefined (reading 'body') only happens when server preset's typeDefs.generated.ts is used.

I'll look into fixing this issue so the correct error is shown, rather than seeing meaningless message like this.
