Description of the problem:  
Hello,  
I keep getting “Unspecified JavaScript error” when I run the experiment online. After the program finished downloading the resources in the beginning, the error pops up.

What I have tried to do:  
I tried to match between the platform version on Pavlovia and Psychopy version in Bulider window but that didn’t work.  
I would appreciate any help.  
Thank you!

HI, do you found a solution for this error? I have exactly the same and tried a basic task (intro and keypress) and even this doesn’t function at all…
