Description

I have an OpenAPI spec for which I can build a working Python client without errors using npx openapi-generator-cli generate. In our bigger project setup we use the Gradle plugin to generate a variety of clients for our API. In this setting, the generated Python client is exactly the same as the NPX CLI version, except for a syntax error due to a missing newline (see example below).

class DefaultApi:
    ..
    @validate_call
    def get_root(..):
        ..
        _response_types_map: Dict[str, Optional[str]] = {
            '200': "object",
        }        response_data = self.api_client.call_api(  # Note the missing newline here (before response_data)
            *_param,
            _request_timeout=_request_timeout
        )
        ..
    ..

The spec given here is a minimal example, but for a bigger spec the error repeats itself across all API operation methods, i.e. wherever the response_data = .. statement appears. The client built using NPX does not have this issue.

Clueless as to why this happens with the Gradle plugin. Any help is much appreciated!
