Volt rb framework unable to connect to database

when I fire volt server in the terminal, it gives me this error message

Unable to connect to the database. Volt will still run, but the message bus requires a database connection to setup connections between nodes, so the message bus has been disabled. This means updates will not be propigated between instances (server, console, runners, etc...)

It didn't use to do this before. Even if I delete the repository, generate a new one, fresh, clean, untouched, it still gives me this error. Do I need to install a mongo DB viewer?
