Connecting MLab MongoDB to Rasa Core

Rasa Open Source
1

I keep getting the following “Authorization” error when I run docker-compose on a simple rasa set up with 3 containers: Rasa_NLU, Rasa_Core, and action_server

the core has access to an endpoints.yml file, which contains the following tracker_store code w/ actual values of course:

tracker_store: store_type: mongod url: mongodb://ds<unique_num>.mlab.com:port db: rasa username: “username” password: “password” collection: conversations

I change the url and get back that there was a timeout error, so pymongo is definitely reaching the url, it’s just not getting past the authentification.

PS: I am positive that my tracker_store information is correct/

I am having the same issue with the MongoDb tracker store. I am able to connect to MongoDB (Mlab) through command line but not getting a authentication problem which running docker-compose. Can anyone suggest what to do ?

I managed to do it. This the code for tracker_store in endpoints.yml

tracker_store:  
        store_type : mongod
        url : dsXXXX.mlab.com:XXXX
        db: databasename
        username : username
        password : password
        auth_source : databasename

I added auth_source: databasename and it worked. They should update it in the documentation.
