ResourceOwnerPasswordCredentials(app) fails with Unknown option config_prefix error

[cchayden]

In pymongo 3.7.1 the MongoClient no longer accepts a keyword parameter config_prefix. This causes a failure when executing ResourceOwnerPasswordCredentials(app) I am not sure whether pymongo has a replacement for this functionality, but in any case it causes the whole system to not start up.

I subclassed ResourceOwnerPasswordCredentials and modified the init_app method to omit that parameter. Is there a more elegant solution?

Here is the stack trace:

I was having the same issue... Apparently it has something to do with the flask-pymongo version that is not compatible with Eve's most recent version. I fixed it by running:

pip install flask-pymongo==0.5.2

[rmlopes]

pip install flask-pymongo==0.5.2

Also, werkzeug must be < 0.14.1 and Redis < 3.

Trying to upgrade/use Eve 0.9.2 and I see the same issue currently. Any recent information what versions are currently needed for flask-sentinel to work with Eve 0.9.2 for flask-pymongo, werkzeug and Redis?
