403 Forbidden error when trying to run the experiment online (on pavlovia)

URL of experiment: https://run.pavlovia.org/jeong9793/test1

Description of the problem:
I am getting a 403 Forbidden error message when I try to run/pilot my experiment on Pavlovia.

I did export HTML before creating the project, and I have no idea where I am getting an error from.

Are you logged in? I get that when clicking on someone else’s experiment link.

Also, I think you may get that error if the experiment isn’t running or has no credits

You do have to pilot from Pavlovia rather than the runner.

Have you checked that the files have been uploaded?

Thank you for your reply. I am logged in to pavlovia, and have about three credits assigned to the experiment. When I click “view code”, the folder containing the psychopy file and HTML folder is uploaded…

It looks like your experiments is in a directory called list1 inside a directory called test1.
PsychoPy/Pavlovia assume that there is one experiment per directory.
Your test1 repository currently contains all manners of document, together with a desktop.ini and a ixplorer.exe.
I would encourage you to delete that experiment and try again in the manner I recommended.
Does that make sense?


Last time I made a project, I did from the builder view in Psychopy, which required the local root folder to be desktop – that was why there were other unrelated files and folders in the repository.
So I created a new project in the Gitlab and pushed files using cmd, so that the repository only contains the files in the list1 folder, and now I can run the experiment online. Thank you!


My pleasure.

Happy experimenting!

I am having a similar issue. I am not getting the 403 forbidden message anymore. But I get stuck when I try to pilot the experiment and it doesn’t upload the stimulus. If I press OK it shows the instructions but then it gives an error message. I tried this solution but not sure what I am missing.

Are you getting an unknown resources error? That’s very common at the moment for people unfamiliar with the 2021 method of attaching online resources.

No. It just stays synchronizing forever. I tried forcing the application to quit and when I do it says PsychoPy (not responding). In this case I have two folders. One for the practice videos and one for the task videos. I tried to upload them in the repository but it doesn’t let me either. I would have to to it one video at a time.

I created the folders for the video files on the repository and I’m uploading each video individually. It’s a long process but it seems it will work that way. Fingers crossed.

I’m guessing your videos are very large. This sounds like an unstable way of syncing so I suspect that you may have more issues later.

There are 119 short 2-4 sec videos (8-10.8Mb). I guess the issue is the amount of videos more than the size of the videos. Although some were more than 10Mb. Do you think those are the issue? I could try trimming them and make them shorter. I left it syncing and went to sleep for a few hours. I just piloted it and it gives me the following error shown in the pic: "Undefined is not an object (evaluating ‘this._movie.play’).


Hi! I’m having the same issue and I cannot seem to localize it yet. This is the link yo my experiment: https://run.pavlovia.org/machorka/music-mood-2 . Any help would be appreciated.
