When you are importing or recording traffic,
sometimes the request may contain an
Accept-Encoding header that determines certain compression of the received response data.
In this case the received data may seem corrupted in the UI of Test Studio for APIs.
If you want to view the real content of the response, you should remove/delete the
Accept-Encoding header as shown in the screenshot below.
This suggestion is a temporary workaround. Built-in support for automatic response decompression is coming soon.
