cannot start : shell and server versions do not match

[rmdes]

Since last app package upgrade it seems Wekan cannot start after the upgrade :

Nov 09 15:43:54 MongoDB shell version v3.6.3
Nov 09 15:43:54 connecting to: mongodb://mongodb:27017/c700f370-3683-415d-ad33-e4c9fd933be3
Nov 09 15:43:54 MongoDB server version: 4.0.19
Nov 09 15:43:54 WARNING: shell and server versions do not match
Nov 09 15:43:54 WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 0 })

@rmdes Ah good catch. The issue here is that the app's docker container has mongodb 3.6.x client packages installed whereas the mongodb server on Cloudron is a more recent 4.0.x.

Fix is to update the mongodb client packages on the base image to 4.0.x.

I have fixed this for the next base image release (whenever that is). For the moment, the warning can be ignored since the shell is compatible.

I found restarting Mongodb service manually fixes the error. Or maybe it was just a coincidence.
