Incorrect ScopeMissingException

Trying to connect to a scope using the attached code will return a ScopeMissingException (when the scope is actually present) with the text Couchbase.KeyValue.ScopeMissingException: Cannot locate the scope {scopeName}. Furthermore, the unformatted {scopeName} in the output should display the name of the scope trying to be accessed.

In my example, the scopes present are userData (with collections "users" and "flights") and _default. I tried entering the scope name manually as one usually would first, with the same result. .DefaultCollection() seems to work fine (although it isn't async, unlike the general call)
