When I run Psychopy online, an error occurs after entering personal information

URL of experiment:
https://run.pavlovia.org/Cracker/spt_vpt_expne/?__pilotToken=c9f0f895fb98ab9159f51fd0297e236d&__oauthToken=662b34c785d76a9c9f1e66754ce1aa29af1884f177238b5dd3ab62ae23b3bf35

Description of the problem:
I created the experiment in Psychopy builder(v2021.2.3) with a few code components inserted and it ran smoothly locally. I used the built-in function to convert the python script to Java script and uploaded it onto Pavlovia. I was trying to pilot the experiment and it simply doesn’t work.

error messages:


Does anyone know how to solve this problem, thanks a lot
