OS: macOS Tahoe 26.0.1
PsychoPy version: PsychoPy 2026.1.3
Standard Standalone Installation? Yes
URL of experiment: exp [PsychoPy] and exp [PsychoPy]
Do you want it to also run locally? No, running it on Pavlovia.
What are you trying to achieve?:
I am trying to run an online PsychoPy/Pavlovia experiment that includes movies and webcam recording/media data upload. The experiment was running before, but now it fails online during/after a movie when trying to upload media data.
What did you try to make it work?:
I synced the PsychoPy project to Pavlovia/GitLab again. I checked that the .psyexp and .js files were updated in GitLab. I also tried running the experiment again after pushing the updated files. The same issue still occurs.
What specifically went wrong when you tried that?:
When I run the experiment on Pavlovia, it starts, but after the first movie/media-recording routine it fails while uploading media data. I have 4 recordings of 8-11 minutes each, and 8 of around 1 minute each. First two recordings of 1 min each were uploaded but after that the next big one throws an error. The error message is:
Error
Unfortunately we encountered the following error:
-
when uploading media data for experiment: avisha/memory_eyetracking_test_v2
-
SyntaxError: Unexpected token ‘<’, "
Try to run the experiment again. If the error persists, contact the experiment designer.
Another time I just opened the dashboard and got this error "Error when authenticating the designer
>>> SyntaxError: Unexpected token ‘<’, "
If the error persists, contact Pavlovia’s administrator.

There were some authentication issues too initially, so I created a new experiment (v2 link above) but v2 also had similar unexpected token issues.
