can´t upgrade -> Unable to initialize MongoDB

[Pappmann]

Hi,
i want to update nodebb to latest master, but cannot upgrade to latest git version:

/nodebb# git fetch
/nodebb# git reset --hard origin/v0.9.x
HEAD ist jetzt bei 34a725c Merge pull request #4013 from machado2/v0.9.x
/nodebb# ./nodebb upgrade
1. Bringing base dependencies up to date... OK
2. Updating NodeBB data store schema.
