Unknown resource error online: something strange

URL: MorhT1 [PsychoPy]

I have an experiment where I assign a certain sequence of conditions file to my participants. However, I am getting the unknown resource error when I need to access the conditions file online. The conditions files are all pushed on Pavlovia, so this is not the issue.
I think it can be related to the code I use to assign participants to a certain sequence of conditions:


However, this code is used in one of the IAT demos and it works fine! I am not sure why this issue occurs. The variable order = random is embedded in my Experiment settings.
