disabled with "class heritage GWorkspaceAnimation.MonitorGroup is not an object or null" error

[stollem]

I can't get wsmatrix to work on my desktop - I get the following error message in journalctl (the first two lines may or may not be related).

May 24 09:36:25 xxxxxxxxxxxxxxxxxxxxxxxxxxx gnome-shell[5885]: Some code accessed the property 'WORKSPACE_SPACING' on the module 'workspaceAnimation'. That property was defined with 'let' or 'const' inside the module. This was pr
eviously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code a
nyway.

+1 for me. Is there something I can do to help the debugging?

[mzur]

Which OS/distro, GNOME Shell version and extension version do you use?

[stollem]

For me it was Debian with Gnome Shell 41.3 and extension version 33. It seems like since I filed this bug, I was updated to gs 42 with wsmatrix 34 and the issue has been resolved as a result.
