Uploading builder experiment on pavlovia


I have finished building my visual search task experiment on the builder interface and I am now trying to upload it on pavlovia to run online. Now that I pressed the sync button I got this error:

File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.6/psychopy/experiment/components/code/init.py”, line 231, in writeRoutineStartCodeJS
TypeError: str returned non-string (type NoneType)

and I do not know how to proceed or what exactly this errors means.

Thank you

What version are you using?

I think I was using a previous version os Psychopy3. So i downloaded that now and I tried to upload my psyexp file on the builder of Psychopy3. But it is not running now and I get this error:

File “/Users/veronika/.psychopy3/versions/psychopy/visual/basevisual.py”, line 16, in
from statistics import mean
ModuleNotFoundError: No module named ‘statistics’

Experiment ended.

Shouldn’t the psyexp file run normally on psychopy3 version as well?
