403 error and unable to find sound files

URL of experiment: next condition 2 [PsychoPy]

Description of the problem: Hi there,
I have created an experiment which works perfectly fine on psychopy, however everytime I click the link or try to pilot the study a 403 error comes up. The experiment is in the “view code” section. I think its something to do with the sound file not being uploaded and thus cannot be recognised but the sound file is within the same folder. After running it a couple of times I then got a different error message of this

any help would be very much appreciated

If you have resources set in code then you need to attach them via Experiment Settings / Online
