Export HTML and unknown resource issue in Online experiment

Hi,
I’ve just uploaded a simple test. It works fine on windows 10 (PsychoPy 3.0), but when I tried File - Export HTML for Builder experiment, it stopped at ‘Generating PsychoJS script…’ as following:


It also does not create an html folder when Builder exports HTML and create the JS code.

But I checked my Gitlab and it seems all the files are there:

And when I tried to pilot the experiment, I encountered this:

I’m not sure whether do I export HTML successfully… And I also can’t figure out what causes the unknown resource problem…
Any help would be much appreciated!! Thank you. :sob:
