• Now instead merging 2 different responses as available options, will check for the status code the available options, after that if you still have multiple content types it will raise the error, and users should specify in headers the correct one

Thanks @carloscbl!

Tests are failing though. Not sure if this is due to an issue with your code, or because the failing tests depend on the old behavior.
