Unknown Resource Error Pilot Run

URL of experiment: PrisonersdilemmaToneRillingFullJava [PsychoPy]

Description of the problem: Hello. When I attempt to pilot my task in Pavlovia it seems to get stuck at the point in which the program should be pulling the first external image from the Resources folder. Here is a picture of the error:

I have properly exported all experiment materials including images and conditions file to gitlab where it is easily located and accessible in the Resources folder subsumed within the html folder. I would appreciate any help I can get on this issue. Thank you!
