See screenshot for actual error. This was sent via text to the student who sent the participant the link.
In the datafile, all of the trials are recorded. It must have happened right after the last trial of the last part. But it did not redirect to our Qualitrix URL, which is the last step.
I don’t think they closed the tab as they were able to screenshot this error. Also, I don’t think they can interrupt the study (apart from hitting the escape key which would end the study and generate a different kind of message, at least that’s what happens during piloting).
Two people have completed it since this error with no problem. Is it OK to continue the study? Is this likely to recur?
