Sync Issues with Pavlovia – Stuck on Initializing Screen or 403 Error

[ilkekav]

Hi everyone,

I’ve been encountering an issue while trying to sync my project on Pavlovia using PsychoPy. At first, I got stuck on the initializing screen, and other times, I received a 403 nix error.

Here’s the context:

• I initially created the experiment in the latest version of PsychoPy.

• I then downloaded and switched to an older version (2021.2.0), which I’m currently using. I suspect this might have caused some confusion.

-Now I tried again and this is what I got:Traceback (most recent call last):

File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.6/psychopy/app/pavlovia_ui/project.py”, line 166, in submitChanges

AttributeError: ‘NoneType’ object has no attribute ‘project’

-I tried deleting git folder, reinstalled psychopy but didn’t work.

Has anyone else experienced this? Any advice on how to resolve this sync issue would be greatly appreciated!

Thanks in advance for your help!

Why did you pick 2021.2.0?

It’s on my list of versions to avoid PsychoPy versions to avoid

if you want to use an old version, try 2022.2.5 or 2021.2.3

Here are some possible solutions. Have you removed html from Experiment Settings / Online / Output path?

Quit when trying to open experiment + won't sync

Hello, I had this experiment running both on my locally and on Pavlovia a couple months ago. I just re-downloaded it to modify it to run with younger children and updated to the newest version of PsychoPy. The experiment currently won’t run locally, however when I download from my existing projects from Pavlovia, I cannot run those locally either although they seem to be working fine on Pavlovia. (url: Pavlovia). This is why I thought I’d give it a go and see if I can run it if I upload to Pav…

Can you create and run a very simple fresh experiment in 2021.2.3?

@ilkekav

I couldnt even open the psychopy

To clarify – can you create new experiments? “the psychopy” could mean “PsychoPy” or “the PsychoPy Builder file”? If you mean the latter then please do upload it to this thread.
