Error in COTG application

I get an error when opening a form in the Windows app but this doesn’t happen on the Mac app.

In the application console, the error is:
18

Any ideas?

I suspect the Windows version of the COTG app uses IE as the embedded browser as I just read this (and I was using Bootstrap 5.0):

Internet Explorer

Internet Explorer is not supported. If you require Internet Explorer support, please use Bootstrap v4.

So it seems the probably was sat between the keyboard and the chair (quite literally). :laughing:

Thanks for the heads up and glad you figured it out. I’m currently also working on Bootstrap 5 based forms.
