Hey, thanks for creating an issue for this. I will take a look as soon as I can.

Hey, are you able to provide a bit more context of what are you seeing from your side, like how is the error presented in your case.

Hey @zhukeev this seems to be an exception coming straight from the SDK, not a problem from the library. In any case, digging a bit online I found this SO thread that might help you solve your issues.

As a bonus, I've added a test for checking GZip compression in #114 . This test takes the approach recommended in the thread I just linked and worked like a charm for fixing the exception you were having (from what I could reproduce).

As this is not exactly the library's fault, I'll close the issue and pin it for others in the future.
