Cannot upload to Pavlovia

Description of the problem:
I’m unable to sync any of my experiments with Pavlovia. This error repeated for two users on two different computers.
I get the next output:
“Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\builder\”, line 1221, in onPavloviaSync

Anyone encountered a similar problem and fixed it?
Thanks in advance,

Looks like the same issue as Psychopy is not syncing experiment to Pavlovia - #2 by jon
Let’s handle it just in that one place. Could you tell us (there) what version you’re using?
