Encountered error when trying to sync the project on psychopy builder with pavlovia

Hi! I have encountered a problem trying to sync an experiment from Builder to Pavlovia. The experiment runs well locally on my computer; I have created a folder for only the .psyexp file and relevant resources, ‘index.html’ file, an ‘experiemnt.js’ file, and an ‘experiment-legacy-browser.js’ file.

When I try to sync the experiment on the builder with pavlovia, I get the following error message:
