Error to run experiment online (Image-Text Stoop)

Online experiments

URL of experiment: Pavlovia

Description of the problem: Hi, I am using Mac and version 2021.2.3 of PsychoPy.

In builder, my Image-Text stoop experiment works perfectly. However, when I try to run it online, the system shows this error:

Unfortunately we encountered the following
error: ReferenceError: None is not defined
Try to run the experiment again. If the error persists, contact the experiment designer.

I tried to upload the same project from Windows, but the problem persisted. How to fix that?

Thanks in advance!

Hello arman-y

if you search the forum with “error: ReferenceError: None is not defined” you’ll find a couple of posts with the same error message. At the moment you provide too little information to get more focused help. But I guess that your problem will be among these posts.
