Unable to run an experiment on localhost and Pavlovia

URL of experiment: Pavlovia

Description of the problem:
I built an experiment that runs fine with Builder in 2024.1.5 and now running fine in 2024.2.1, and also generates the corresponding .py and .js scripts. Despite this, I can’t run the experiment on localhost (I get an error that Safari can’t open localhost because the server dropped the connection).

I also synced the experiment on Pavlovia, but when I try to run it in Pilot mode, I get a different error (see attached).

What does image10 look like?

Have you added the resources in Experiment Settings/Online ?

Is it set to constant when it should update each repeat?

[sorry, but I can’t help with your localhost issue]
