OS: Mac (10.14.6)
PsychoPy version: v2020.2.10
Standard Standalone? (y/n) If not then what?:
I ran a pretty simple experiment in Builder and online (worked great in both but because the Rating component isn’t supported in JS, I added a Slider in Builder. After adding this, the whole thing stopped working and I got an internal error (see below)
What did you try to make it work?: I tried disabling the Slider component and then removing it altogether.
What specifically went wrong when you tried that?:
