Okay. So, yes, it does seem like I was missing a step. It seems like the local debug mode will not run anything until after the experiment has been pushed to pavlovia. Not sure if this was the expected behavior, but hopefully this this thread will help future readers.
PS
- This was also the case with the standalone version on Windows 10 (2020.1.3)
- I haven’t actually been able to run the experiment in local debug mode. Although a browser now opens up (chrome), the opened page never moves past “initialising the experiment…”, giving the error copied below. But at least it looks there are a few other threads about similar phenomena.
