Participant data files have not saved

Online experiments
1

I’ve just started running my study online on Pavlovia (in running mode) and I’m having an issue with the participant data. Out of 12 participants, only one data file has been saved. Two other data files appear to be in the data folder, but they are empty. With regard the other 9 participants, there is just nothing showing at all. The log file is empty also.

I’m not sure what to do, as when I have tested it myself (in running mode, from Pavlovia) the data saved fine. Can anyone please give me some tips on what might have gone wrong? And is there any way for me to recover the files?

Some more info:

  • my experiment daisy chains from pavlovia → qualtrics → prolific → pavlovia. This is the link I have to take participants from qualtrics to pavlovia: [user name]prolific_squared_tasks?participant=${e://Field/ResponseID}&id=${e://Field/PROLIFIC_PID

  • the participants are showing as completed on prolific, so I am assuming they completed the study

  • the appropriate amount of credits have also been consumed on Pavlovia.

Thanks very much in advance.

Update: Okay I think I have fixed the issue. I was missing a curly bracket at the end of my redirect link. But I also had a / in my Data filename field in experiment settings (it is now ‘%s_%s_%s’ % (expInfo[‘participant’], expName, expInfo[‘date’])).

Just thought I would update in case this helps anyone troubleshoot in the future. Although this kind of mistake could just be a me thing!

Changing the data filename doesn’t work online.
