Description of the problem: A participant completing the above study, in Chrome on Mac, received an error at the very end of the experiment (see screenshot below). Other participants have completed the experiment successfully, and there are plenty of credits assigned to the relevant experiment. I have found reference to the same error in other threads (e.g., here), but no information on the cause or a means of preventing its recurrence. Any help along these lines would be appreciated—the experiment is quite long so losing data after a session is complete is a bit of a nuisance.
