Over the course of 3 days I get this error about 20,000 times.

$ journalctl -b | grep "DockManager.getDefault() is null" | wc -l
18419

It occurs in sets of about 76 errors with the same timestamp.

$ journalctl -b | grep "DockManager.getDefault() is null" | grep "Jan 12 22:20:20" | wc -l
76

One instance of the error:

I uploaded the first 1MB of gnome-shell messages including stack traces to the following gist. https://gist.github.com/blsz/af959a84b7120270b632de15bb1b3969

Update: There are no errors when dash-to-dock is the only enabled extension. Enabling other extensions, including but not only "vertical overview", produces many errors. The design of the gnome extension framework allows for adverse interactions between extensions.

Update 2022-03-18: There are no more TypeError: DockManager.getDefault() is null errors with Gnome 41 and dash-to-dock installed from git. At this point, I see only one type of JS ERROR, Actor not in scroll view, which coincides with opening and closing Gnome Terminal windows.
