@sinoon can you export this Map Local Rule and share it with me via support@proxyman.io ? I'd like to investigate why it shows this error 👍

@sinoon Let's remove the Transfer-Encoding: chunked, it causes the bug.

I will automatically remove this header from the Response.

If you create a Map Local file by right-clicking on the Request -> Tools -> Map Local -> It automatically clears some invalid headers.

However, if you manually select the file from your Mac, it doesn't clear.
