Error: TypeError: Cannot read properties of undefined (reading '0')

URL of experiment: Normal [PsychoPy]

Description of the problem:
Im having a problem with my experiment, it works well when trying in psychopy.
The problem occurs in line 1785 and I cant figure out how to fix it. If you need any further information Id be glad to provide it. Im a total newbie when it comes to coding and creating experiments in psychopy/pavlovia.
Your help is much appreciated
Kind regards

Hi Dom,

Thanks for engaging with the forum! A good start point is to make a minimally working example if possible , this will really help us pinpoint the issue.

So, for example, if that error occurs at one specific point/routine in your experiment, can you remove all other routines so that we can see specifically where it occurs. For instance here I am afraid I do not understand German, so I can’t get past the first screen to get to the point where the error occurs. If you could make a stripped back version of the task that would be very helpful.

Best wishes,
