"Unknown Resource" online, but works fine offline?

[wakecarter]

I have a few minutes to write a reply now.

I have one experiment still using the html folder where I have set “Use PsychoPy Version” to 2020.2.3 in Experiment Settings.

For another experiment what I did was:

1. Close the experiment in Builder.
2. Download any existing data from Pavlovia.
3. Delete the repository from Pavlovia.
4. Delete the local .git folder.
5. Delete the local html folder (after removing any files than only exist in it).
6. Delete other unnecessary local files.
7. Open the experiment in Builder.
8. Check that Experiment Settings / Online / Output path is blank and Export HTML is on Sync.
9. Press the “Sync with web project” icon to create a new project online.
10. [Added 21 Feb 2022] If you now get an unknown resources error attached any resources defined in code via Experiment Settings / Online / Additional Resources in Builder.

Unknown resource - xlsx file. Have tried adding to Additional Resources

This is an odd list of steps. What I did a couple of days ago when faced with this issue was: Downloaded existing data from Pavlovia. Deleted the project from Pavlovia. Closed PsychoPy. Deleted all local files and folders from the experiment apart from the psyexp file and resources. Opened the psyexp file in PsychoPy. Checked that the output path in Experiment Settings was blank. Pressed the sync icon to create a new project online.

Online experiment "Unknown Resource" issue

In 2020.1 PsychoPy created an html folder for index.html and the javascript files. It also copied resources to html/resources and loaded everything in that folder into memory at the start of the experiment. If you needed a resource that was only mentioned in code you could just copy it to html/resources to tell PsychoPy to load it. This was inefficient because it meant that most experiments had two copies of its image, sound and video files which could nearly double the disk space used. From …
