This Rails project reproduces the Zlib::GzipFile::Error error that response body from Google API is already unzipped, but the header is still saying that it's 'gzip' encoding.
Which causes httplog to raise exception, because it tries to unzip the already unzipped body.
To see the error, just run the Rspec tests.
Running that test generates for me the following output:
