Can't start the extension. Has a TypeError in the log.

I installed the extension using the Firefox plugin for Gnome Extensions. It has worked once. After I logged in again today, the extension doesn't work anymore. This is what it says in the log file:

If I comment out line 2184 the extension will load and it will show the buttons in the bottom bar. No side effects so far.

Seems to be the same bug: https://github.com/zpydr/gnome-shell-extension-taskbar/issues/192

[c0ldplasma]

Which distro and GNOME version are you using?

[NLSurfMan]

Yeah, that might be the same bug.

Fedora 32 Workstation Gnome 3.36.4
