Receiving 401 without body does not throw an error about graphql-mesh HOT 4 OPEN

A bit more context : it seems to happen only for operations with a return type marked as "JSON"

Examples :

query me { identity: GetUser { id } } 
=> I receive an error
"errors": [
    {
      "message": "HTTP Error: 401, Could not invoke operation <redacted>",

query systemStatus {
  SystemStatus
}
=> I do NOT receive an error
{
  "data": {
    "SystemStatus": ""
  }
}

The only difference I can see is that the query SystemStatus is defined like SystemStatus: JSON whereas the query GetUser has a "proper" return GetUser: UserInfo

Could you give more details about your setup? What kind of source are you using? OpenAPI? SOAP? GraphQL?
For GraphQL, GraphQL Mesh forwards the response as-is.
For OpenAPI, only if there is a response for 401 status code, GraphQL Mesh returns the exact response. GraphQL Mesh throws an error if there is no defined response in the OpenAPI spec for that specific status code.
If you don't want Mesh to handle other status codes, you can set ignoreErrorResponses: true so in that case Mesh will only handle 2xx status codes, and throw others.

I'm using OpenAPI

Below is the extract of the OpenApi for both operations (they are in the same source)

note : I cannot provide the whole doc as is, I'd need to clean everything except these 2 operations, please ask if needed

None of them specify the 401 return code, so it should throw based on your explanation

I do want graphql mesh to handle the described errors (like "400" for example) so I do not want to use ignoreErrorResponses

I'm attaching the logs of Graphql mesh for both queries (I redacted the URLs, the tokens, ...)
logs-graphql-mesh.zip

you will see that the server answers the same response in both cases but the difference is at the end

Extract for the systemStatus
🐛 🕸️  Mesh - Identity - Query.SystemStatus   => Return type is not a JSON so returning 

Here is the relevant OpenApi

/systemSstatus:
    get:
      operationId: SystemStatus
      responses:
        "200":
          description: Success
          content:
            application/json:
              schema:
                type: object
                additionalProperties:
                  type: boolean
            text/json:
              schema:
                type: object
                additionalProperties:
                  type: boolean

/user-info:
    get:
      operationId: GetUser
      responses:
        "200":
          description: Success
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/UserInfo'
