Description of the problem:
EasyEyes is built atop of PsychoJS. I ran an EasyEyes experiment in class with 20 students. I gave them the study URL (above), which they typed into their browsers. It worked fine for nearly everyone. One student, on a MacBook Pro got this fatal PsychoJS error (see screenshot), which is new to me. My hunch is that Pavlovia’s Gitlab couldn’t handle two instances of PsychoJS (i.e. two students) uploading data at once. Is that right? Ideally PsychoJS would pause and try again instead of just dying without saving the data.
P.S. When I downloaded all the data I did find a 606KB CSV data file for CrazyForestPear249, so it appears that most of her data were saved. Phew! Even so, the fatal error is worrying. If she’d been recruited online she wouldn’t be sent back to Prolific with a completion code, and might not get paid.
