Run test on Pavlovia: Blank page. Failed to load resource: the server respond with a status of 404

URL of experiment:
https://run.pavlovia.org/suwangcn/train_transfer_simon_baseline/

Description of the problem:
I never encountered this problem before. Recently, I updated my PsychoPy to a 2024 version, and the new test program (the one in the URL link) is actually copied and modified from my previous test. However, this time, when I run the experiment on browser, there is nothing like “initialising the experiments” on the screen, and the Javascript error shows “Failed to load resource: the server respond with a status of 404”. The program can run very well locally with python code. I am not sure what happened this time and looking for some help.

This should help

Thank you for the solution!
