Psychopy error when uploading to pavlovia

Version: 2021.1.4
I am trying to sync my psychopy experiment to pavlovia and an error keeps popping up. The experiment works in builder mode just fine but says this error when attempting to sync:

Traceback (most recent call last):

KeyError: “[‘rating’, ‘triangleMarker’]”

It worked fine yesterday but today is not. I tried making a new folder without any unnecessary files already, but that didn’t work.
Please help. Thank you.
