Online piloting stuck on “initialising…”

OS: Win10
PsychoPy version: 2024.2.4
URL of experiment: Pavlovia

Description of the problem:

Dear experts,
I am trying to pilot test my experiment in Pavlovia and keep getting stuck on the “initialising…” screen even if it runs well offline. I can’t find any error message…
Can you please help me with this?

Thanks
Arnaud

The answer is in the thread you linked to. You are trying to import the Python library random. It probably shows an error in your code component in Builder.
