Slider not working Pavlovia - TypeError: this._style.forEach is not a function

Hi,

I’m trying to implement a simple slider onto Pavlovia from Psychopy. However, while it works fine locally, when I try to run the experiment online it crashes immediately, with the following error:

  • TypeError: this._style.forEach is not a function

This is particularly weird as I can’t find ‘this._style.forEach’ in the Python or JS code!

Any suggestions for how to fix this, or how to implement a slider in any way without this error, would be greatly appreciated! Thanks a lot :slight_smile:

Hi There,

What version of PsychoPy are you using and, if a recent version, do you have any special styling options used under the “appearance” tab?

Thanks,
Becca

Hi,

I’m using Psychopy3 (on a Windows laptop, in chrome browser). No, this happens even if I just put in a slider component and don’t alter it at all!

Thanks
