10 months ago The error shows up most of the time but sometimes it doesn't show up. Today I ran 8 participants, and all made it to the end. Then I tried running 30 participants and the experiment crashed in the middle. But the server usage (CPU, disk, memory) looks good.
This is the error I got:

Is there an existing issue for this?
What happened?
My experiment runs fine for a while (participants can log in, are paired with other participants, etc.) but then in the middle of the experiment it crashes and participants are not able to continue.
This has happened twice, once when I was running version
1.4.6and once with version1.8.0After I get this error, if I
empirica servemy bundle file again, it gives me more errors:The errors disappear if I delete the
tajriba.jsonfile and then redeploy the experiment.Steps To Reproduce
