Graphql-code-generator: 1.8.3 Broke loading schema from URL (with env variables)

[qw-in]

Describe the bug
As of 1.8.3 now get error when trying to introspect from url with env variables

✔ Parse configuration
  ❯ Generate outputs
    ❯ Generate ./packages/server/src/<thing>.ts
      ✖ Load GraphQL schemas
        → Failed to load schema
        Load GraphQL documents
        Generate


 Found 1 error

  ✖ ./packages/server/src/<thing>.ts
    Failed to load schema from [object Object]:

    undefined
    undefined

    GraphQL Code Generator supports:
      - ES Modules and CommonJS exports (export as default or named export "schema")
      - Introspection JSON File
      - URL of GraphQL endpoint
      - Multiple files with type definitions (glob expression)
      - String in config file

    Try to use one of above options and run codegen again.
    Error: Failed to load schema
        at Object.exports.loadSchema (<__dirname>/node_modules/@graphql-codegen/cli/dist/common
js/load.js:75:15)
    Error: Failed to load schema
        at Object.exports.loadSchema (<__dirname>/node_modules/@graphql-codegen/cli/dist/common

To Reproduce
Steps to reproduce the behavior:

1. My codegen.yml config file:

      headers:

# ...
