Hi, i am creating a stroop experiment to which after they have done the stroop they kept on Pavlovia to complete a questionnaire. The experiement runs perfectly fine online however when i have added a routine to qualtrics to direct to the surveys after they have finished i get the error ‘rel’ when attempting to sync.

KeyError: ‘rel’

I have removed the questionnaire routine and this doesnt appear.  
I have a keyboard element to move on from the end screen.

Many thanks to anyones solutions. xx

Please could you clarify what you have done. Qualtrics doesn’t have “routines” so I’m guessing you mean a PsychoPy routine. However, daisy chaining (moving from one piece of software to another) is normally done via Experiment Settings / Online.

Have you added any code which includes the letters or reference rel ?

Hi there, I am having the same issue.

I have an experiment on PsychoPy that runs and syncs perfectly to Pavlovia to be run online. However, when I add a Pavlovia Survey to the experiment in the builder (linked via survey ID) as a standalone routine, I then get the following error when I go to sync to Pavlovia:

Traceback (most recent call last):

File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.10/psychopy/experiment/components/settings/ **init**.py”, line 1091, in prepareResourcesJS  
KeyError: ‘rel’

If I remove the survey routine from the experiment, it syncs just fine with no errors. Can anyone help me figure out what this error is and what could be causing it?
