Psychopy Unhandled Internal Error

OS: Windows 7
Psychopy 3 2020.2.10
Standalone and Online

Hi everyone

I’m trying to upload a task I’ve been working on which is working standalone on my local machine. Unfortunately when I try to upload it to Pavlovia, I get this:

“Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\pavlovia_ui\”, line 161, in submitChanges
self.parent.project = self.project
AttributeError: ‘NoneType’ object has no attribute ‘project’”

I’ve tried looking at but am unable to trace line 161 or identify the error. (25.4 KB)

If anyone has any pointers I would be very grateful.



I got a same problem just like yours, and i don’t know how to solve ti either.

If you got the answer, could you share with me?

Did you also call your experiment project?
