PsychoPy upload to Pavlovia - html file missing

Hi there, I completed an experiment on Builder that had no code, a straightforward image only study. When I tried syncing it with Pavlovia and clicking “pilot”, I got a 403 error message. I think this has something to do with the html file. The platform version also remains 0 which I think is an issue. Any suggestions? Thank you very much!

This happened to me, what I did was shut everything down and restart psychopy. I also noticed that the file was uploading the wrong stuff, so I put everything in a separate folder on my desktop and that worked.
