The experiment was syncing normally before, while my PsychoPy version was not updated to the latest one.
The experiment was built in version 2022.2.4 and my current version of PsychoPy is 2023.2.1. Error is there when I try ‘Use version’ to be both 2022.2.4. and the latest version. What I noticed is that upon every sync attempt, the _legacy version of the experiment is automatically created:
I also have a similar problem but with different versions. I used version 2023.2.2 to build the exp and after upgrading to 2023.2.3 a few days ago, when doing some minor changes and trying to sync, PsychoPy thinks its a new exp. I deleted the older experiment from Pavlovia and deleted all the git / JS related files in the local folder. Synched again and created a new version with a new name. Now there is no Software Platform or version present. I get the same error when trying to run.
