Exception in handle_response method while attempting to decode response content

[d3corator]

I just came across Treblle and wanted to test it locally. I am trying to integrate it into a DRF project, but the library is throwing an exception inside the handle_response method, while trying to decode the response object.

On this line it is trying to process the following byte content

and here is the error
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte

I am simply trying to integrate Treblle into an existing DRF based project and everything else is working perfectly so not sure about what may be wrong.
