ID particpant for OSweb experiment
I have set up a Dot-probe-task in OpenSesame that I am running in JATOS from OSWeb.
It is a larger study, where participants are recruited by a panel provider (let’s call it companyXY).
Participants go through a screener on the company’s website and are the redirected to JATOS via the following link:
Where [UID] is replaced by the company with their ids for every participant.
Analogue to the description on end page / redirection here (https://www.jatos.org/End-page-after-your-study-finished.html) I configured the End Redirect URL in JATOS as follows
where UID is supposed to be the same as in the starting link.
Unfortunatley, the id variable is not included at the end, the company reports that instead of
they get an “undefined”
I already tried to test whether uid is case sensitive but received the same result.
I would appreciate any suggestions, how this error may be caused
