Error evaluating function floor: argument must be a number

[xkitsios]

Hi! I was updating NodeBB from v1.19.3 to v1.19.5 and I encountered the following error:

I'm also seeing this error - it's preventing NodeBB from rebuilding and starting.

Specifically:

My NodeBB version: NodeBB v1.19.6
It's running as a Cloudron.io app, Cloudron 7.1.4

I can confirm that manually applying the patch referred to above allows it to boot, at least for now. Cloudron is a docker-based deployment so I expect this won't last unless a fixed version is released, or I disable Lavender.

switched to sass in bs5 branch this should be resolved
