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

URL of experiment:

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
