Can't upload experiment to pavlovia,click sync and get error

hi i’m trying to upload my experiment to pavlovia and after i click sync i get this error message. Don’t know what i did wrong and how to fix it. Can anyone help me? Lots of thanks!

Description of the problem:

Traceback (most recent call last):

retVal = pavlovia_ui.syncProject(parent=self, project=self.project)

Hi there,

The error message appears to relate to a slider - do you have any form or slider components?


Hi Becca,
Thank you for the answer. I don’t have sliders. I am able to upload it after i change the \ in my custom code to \. But later when i want to sync I get this error again.

Hi I solved this problem by installing psychopy 2021.2.10. Hope this may help people who encounter the same problem.
