Online experiment survey not syncing with Key error

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.
Traceback (most recent call last):
File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.8/psychopy/app/builder/builder.py”, line 1604, in onPavloviaSync

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 ?
