Hi all,

I have a backend system where the response is compressed and sent , Content-Encoding :deflate.

I have tried to put the compression algorithm property , it didn't work . And when i set the Accept-Encoding header as deflate , i am getting the below error.

Is there something i am missing ? Please suggest.

Is this still a problem?

It seems to me the backend is setting an incorrect content-encoding header: The header does not match the actual content. Please advise if this bears further investigation.
