Description

Is your feature request related to a problem? Please describe.

My OpenAPI spec defines the successful response code as 302 for one endpoint, but the generated client throws an error if the response is not in the 2xx range:

        if (localVarResponse.statusCode()/ 100 != 2) {
          throw getApiException("exportDataResourceById", localVarResponse);
        }

Describe the solution you'd like

Ideally there would be a configuration option to avoid throwing an exception if the response is not in the 2xx range.

Describe alternatives you've considered

Research direction

Start at the openApiGenerate entry point and trace how the Java/Gradle client handles the generated exportDataResourceById response. Determine where response status codes outside 2xx become exceptions and how a configuration option would affect that path. Done means a configured client accepts the specified successful redirect response code without throwing.
