Description of the problem:

I am getting the common _404 Not Found nginx_ error when I attempt to run the experiment on Pavlovia originating from builder. When I run the experiment through the Pavlovia dashboard via Pilot, I receive a _403 Forbidden nginx_ error. I have worked my way through the The [PsychoPy to JS crib sheet](https://docs.google.com/document/d/13jp0QAqQeFlYSjeZS0fDInvgaDzBXjGQNe4VNKbbNHQ/edit), but I am still facing the same issue. I have cloned my files from Pavlovia and made them available [here](https://usu.box.com/s/v3mm71342aacmci7zq0894ui750vv0y5).

Any insight would be appreciated.

Hi There,

I didn’t get the same error as you but did notice some issues that could cause problems.

1. There were a couple of syntax errors in the firs JScode component (I think additional text outside of the function was pasted over).
2. Your movie raised an error - I noticed it is in .gp format - are you able to try converting to some of the video formats recommended on the crib sheet?

I loaded the debugged version here [https://pavlovia.org/lpxrh6/sequential-dot-debug](https://pavlovia.org/lpxrh6/sequential-dot-debug) could you try forking this and seeing if it runs as you expect? (with the exception of the movie, which may need reformatting)

Thanks,  
Becca

Becca,

Thanks for the insight. I’ll reformat the video files (don’t know how I overlooked that component). For some reason, though, the debugged version won’t sync to a project. I keep getting the following error code.

```auto

During handling of the above exception, another exception occurred:

Hi There!

This looks like it could be a problem with the name of the project - are you using any special characters in the name? try to only use letters if possible 🙂
