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:
https://jatos.mindprobe.eu/publix/1234/start?batchId=1234&generalMultiple&uid=[UID]
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
https://www.companyXY.com/studio/st/test/?sprung=ok&var=1&u=[UID]
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
https://www.companyXY.com/studio/st/test/?sprung=ok&var=1&u=1234
they get an “undefined”
https://www.companyXY.com/studio/st/test/?sprung=ok&var=1&u=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

Hi!
First, please no cross-posting between the JATOS and OSWeb forums. It keeps the forum clean and our work to a minimum. And if we notice that the post belongs in a different forum we forward it.
I think you should use 'uid' instead of 'UID' - the query parameter are case sensitive.
E.g. if your study run link URL is:
https://jatos.mindprobe.eu/publix/1234/start?batchId=1234&generalMultiple&uid=abc123
And in the End Redirect URL in JATOS, in study properties:
https://www.companyXY.com/studio/st/test/?sprung=ok&var=1&u=[uid]
And this works only since version 3.6.1. But jatos.mindprobe.org has already this version.
Best,
Kristian
