Participant id undefined and pavlovia/psychopy crashing at end

URL of experiment: colMixWM [PsychoPy]

Description of the problem: Hi, I’m having a weird problem with my PsychoPy/Pavlovia online experiment where at the end of the experiment, psychopy crashes. It gives me the saving results box, but then gets stuck on saving and gives me an error code 5 or “Aw Snap” (Google Chrome). I thought maybe it was a memory issue, but I don’t see anything in my experiment that would be saving extremely large amounts of data. I checked that I don’t have anything logging data every frame…

Also, I have save incomplete results on for my experiment, but when I go to find the data it is sometimes not there. I only have a csv file that starts like this “PARTICIPANT_colMixWM…” that is zero bytes and empty.

I also tried this on a different computer, also using chrome, and got to the end of the experiment, but when terminating, got an error for “invalid string length.” Something also related to logger.flush.
