403 Forbidden Error and cannot view code

URL of experiment: https://run.pavlovia.org/megan.liew/envelope_drag/?__pilotToken=a87ff679a2f3e71d9181a67b7542122c&__oauthToken=9b37a986ffe2650008c32ab0374067e3dc459d9b8c0e27e8e4670f3fe23831fb

Description of the problem:
I have an experiment that has a lot of custom code added to it. When I tried to pilot run the experiment, Pavlovia produced the error “403 Forbidden nginx.” I tried pilot running a dummy study with no code components but the same error was generated. I also cannot view my experiment’s code. I think part of the problem may be due to the experiment in PsychoPy not syncing with Pavlovia. Does anyone have a solution to this problem? Any help is greatly appreciated!
