Compile from builder not working

URL of experiment:

Description of the problem:
I had previously created a psychopy experiment that worked correctly both locally and online. In this experiment, I had specified ‘additional resources’ using the ‘online’ tab of the experiment settings.

Then today, I wanted to copy that experiment and use it in a new folder with new stimuli. First I copied only the .psyexp file. However, it would not compile a .py or a .js file (using the compile buttons from the builder view). The error message was “[ or filename.js] Not a file!”.

So then I copied the .py and .js files from the original folder to the new folder, and I hit the ‘compile’ buttons again.

The problem I have is that the .py and .js files in the new folder do not reflect changes I have made in the builder view. The only important change is the files that I am changing in the ‘additional resources’ area of the ‘online’ tab of the experiment settings. When I try to run the experiment, it doesn’t work because it is looking for resources that aren’t in the new folder.

I am tempted to manually edit the .js file (just the dictionary for resources) but based on what I have read here, that seems like the wrong thing to do. I did try to add a code component with a resources dictionary (in the ‘before experiment’ tab), but again the the compiled .js did not reflect this change.

I read this thread: New version of Psychopy doesn't compile script - #5 by kjj11033

So in the experiment settings, I changed “Use PsychoPy Version” to 2020.1 .

Then I got this error:
