Describe the bug

The output for the exact same openApi Swagger definition (in yml) differs whether it is fetched from an endpoint or read locally by graphql-mesh.
Basically afaics, this issue #2627 still occurs when fetching the swagger

To Reproduce Steps to reproduce the behavior:

I cannot provide a reproduction as our endpoints aren't public, and you need both a hosted and local version of the same file.
Sorry about that :/ Feel free to suggest a way I can help with that.

Expected behavior

Outputted schema to handle nullable: true correctly when schema is fetched from a URL

type User {
  id: String!
  name: String!
  imageUrl: String
}

But the result we get atm is:

type User {
  id: String!
  name: String!
  imageUrl: String!
}

Environment:

• OS: MacOS 14.1.1 (23B81)
• "@graphql-mesh/openapi": "^0.98.0":
• NodeJS:

Additional context

I tried to curl the schema manually, then add the file locally and generate. I then got the expected result.

Hey there, turns out the issue is somewhere else. Still investigating.
Closing the issue for now and I'll open a new one if I manage to identify where the issue is coming from.
