[open] Error while executing inline script

Hi all,

I am trying to run an experiment with multiple rounds, but it always stops after the baseline and gives me the following error.

My hunch is that I am calling a sound or pictures that is not in the pool, but I have tried a lot of asjustments and nothing works.

Thanks in advance
