Using mongodb with an invalid MONGODB_URI results in stack trace #5

Closed andreasolund closed 10 years ago

andreasolund commented 10 years ago

The issue occurs when an application tries to use the mongodb object on a server that has been started with an invalid MONGODB_URI environment variable. E.g starting a Vane server from the DartEditor on a local machine without MongoDB installed.

Stack trace:

Maybe the database manager could check if MONGODB_URI is null on start and prevent applications from using the mongodb object?
