Hello!

URL of code: [Sign in · GitLab](https://gitlab.pavlovia.org/Mi_Lab/dd_test)

I keep getting the following error despite my video file being in the html resources folder. Even with just images, the same thing happens.

 ![Screen Shot 2022-04-27 at 11.24.13 AM](https://us1.discourse-cdn.com/flex002/uploads/psychopy/original/3X/2/3/23c5e51f805f2dc9062b5a5e3e59d27d81b1cf84.png)

I did notice that when I try piloting the experiment, the progress bar does not load at all before displaying this error, so perhaps the resource is not being recognized in the first place? I have checked everything else from other posts (e.g., ensuring the name of the file matches, the file path is correct).

Thank you for your help!

> 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: Close the experiment in Builder. Download any existing data from Pavlovia. Delete the repository from Pavlovia. Delete the local .git folder. Delete the local html folder (after removing any files than only exist in it). Delete other unnecessary local files. Open the experiment in Builde…
