**OS** : MacOS Sequoia 15.4  
**PsychoPy version** : 2024.2.1  
**Standard Standalone Installation?** Yes  
**Do you want it to also run online?** Yes  
**What are you trying to achieve?:** I’m trying to sync a project to Pavlovia

**What did you try to make it work?:** I just finished editing my routines in the test and I was trying to update the test to the one created earlier.

I got this error message below. I went to my Pavlovia dashboard and the experiment is not updated (it has the updated: part as my older version of the experiment)
