Unable to upload experiment to Pavlovia

Hi, I am quite new with Psychopy and I have been running into a lot of problems lately. I was having issues with fixing custom code on Psychopy so it can be run on Pavlovia, so I manually changed some code in the js files on the Pavlovia site, and ever since then, I can’t upload changes of my experiment from my builder to Pavlovia. Every time I try I kept receiving the following error:
I tried to revert the changes I made in the JS files as well as re-uploading a new experiment, but nothing works. Any help would be great!
