Is it possible to check Prolific is routing to Pavlovia and then back for completion without running the study?

I built my experiment in Psychopy and I am hosting it on Prolific. I have followed the guidance here.

However does anyone know if it’s possible to do a dummy check to make sure the URLs are working as intended? I’m happy to run the study on a very small scale, but don’t want to run into issues of participants being paid!

Kind regards,
