Hello,
I tried to change the trackerstore to mongoDB and i followed your instructions in your Docs (Rasa Open Source – API Reference – Tracker Stores), i´m using Docker-compose and it creates the container but it´s not connecting to the mongoDB (there is nothing inside the mongo data base). I also tried with the DynamoDB, following your guide and creating a Dynamo on AWS, but the information wasn´t passing trough also.
FYI, I´m using integrated version control with a github repository to connect the bot code to the Rasa X. I tried changing the endpoint.yml that is in the directory /etc/rasa, but it just stopped syncing with the postgresql but not sending the information to the new dynamo DB for example.
