Trying to push experiment to Pavlovia, getting ERROR 403

URL of experiment: Pavlovia

Description of the problem: I am trying to push my experiment to Pavlovia, but it remains on the “Synchronising… Pushing to Pavlovia for the first time…” window forever. The experiment will show up in my dashboard, but if I try to run it, and ERROR 403 window will pop up.

Another thing I notice is that the software platform is marked as UNKNOWN and the platform version is marked as 0. My other experiments that run properly will say PSYCHOJS and 2023.2.3. Any tips would be appreciated!!!

Check the size of the folder containing the psyexp file (including any subfolders)

Are there any error messages in the Builder?
