Description of the problem: hey! i recently converted some javascript code into psychojs format to run an online experiment through pavlovia (i am very new to javascript/psychojs). while my experiment runs locally and in pavlovia, none of my data saves in pavlovia. experiments all fall under the “aborted” category (despite piloting/running the experiment to completion) and when i download the results, i get a completely empty folder. wondering if anyone may have any tips/suggestions that might help. for context, the saved data should include participant id and the urls visited by participants. i will attach my code. thanks in advance!

Are your participants ending your experiment by pressing the escape key?

> Exit cleanly Locally you might want your participant to end on a thank you screen rather than being sent back to the PsychoPy Builder. Unfortunately, this desire has encouraged a bad habit of leaving the final message on screen and then pressing the escape button to exit. While data is saved locally after escape has been pressed, until recently microphone recordings were not. My recommendation would be to have the final screen end on a key press that you have not told the participant, e.g. ‘q’. …

No - participants are just left on a “thank you for participating” page and should just be able to exit the browser tab.

Closing the browser tab without ending the experiment will definitely lose the data.

yes - when i try other versions of psychojs, it won’t allow the experiment to run at all.

If you are able to install more recent versions of PsychoPy I would strongly recommend that you seek help with getting your experiments working in a more recent version.
