Participant ID from Prolific to Qualtrics to Pavlovia to Qualtrics

You might also be able to solve the error by adding the following code to a Before Experiment JS code tab

util.addInfoFromUrl(expInfo);

Participant info not saved on filename.csv

You might be able to add a Javascript-only code component as a workaround for this issue. In the Before Experiment section of the code component you can add: util.addInfoFromUrl(expInfo); and this seems to force the URL parameters to be read before the participant file is created. I briefly tested this in a minimal example in Version 2022.2.4, but have not tried it in a full experiment yet. Credit to @young1 for first proposing the workaround. -shabkr
