Hi @KarahanGuner, thanks for taking the time to report the problem. Apologies for the delay in responding, I've been away, but I'll look into it and get back to you very soon! Thanks

Hi @KarahanGuner, can you go to https://github.com/xnl-h4ck3r/GAP-Burp-Extension/releases and click on GAP.py under Release v1.9 and load that? I am running Windows 10 myself, and I have just done this to double check and I don't see that error. Maybe you were using an older version? Please let me know if this resolves the issue or not. Many thanks Xnl

[KarahanGuner]

Just checked it, still the same problem. Could it be because my system is in Turkish?

[xnl-h4ck3r]

Hi. I'm not 100% sure. It may be to do with CRLF differences in unix and windows. Can you get this file, and change the .txt to .py (I can't add .py fiels here) and try that version instead? GAP.txt Thanks Xnl

[KarahanGuner]

This one also didnt work. I also tried changing my system language to English but that didnt help either.

[xnl-h4ck3r]

Could you try this one just in case this works? GAP2.txt

[KarahanGuner]

Sorry, still the same error.

[xnl-h4ck3r]

Hi. I'm sorry I'm struggling to work out the cause or solution of this error because I can't reproduce it muself :( When you install it, I assume you get that error on the "Errors" tab of the "Load Burp Extension" window? Is there anything on the "Output" tab (I want to see if the error is occuring before or after the text is written there)?

[KarahanGuner]

I solved the problem after reading this thread: https://forum.portswigger.net/thread/not-supporting-characters-in-extensions-c29438eb

The problem was with where I was putting the GAP.py file. In Turkish "New Folder" is "Yeni Klasör". It was giving this error because of the letter "ö" in the folder name. I just changed the folder's name and it was fixed.

[xnl-h4ck3r]

Interesting! I'm glad you figured it out :) Let me know if you have any other questions to issues Many thanks Xnl
