Error on Editing codachi : window is not defined

Hello, i wanted to edit and add some feature ( that you would agreed or not) but ultimatly it's just giving me a excuse to work on a project.
but when i wanted to call dom.getelement, i saw that my vscode text was not working, here is the branch : https://github.com/scoutantho/codachi

but then when i activated the breakpoint option showned in the screenshot, i get the same error just by running the extension.
So if you have any idea (anyone) how to fix this, or if someone has a branch taht is working fine with no errors at all, i would like to know :)
thanks !
this is the error :


Start by reproducing the VS Code extension error from the linked codachi branch, with the breakpoint option enabled, and inspect the reported “window is not defined” failure around the attempted dom.getelement call. Done means the extension runs without that error; the issue does not name a file or test to run.
