Error in TrackerStore DynamoDB Section

Rasa Open Source
1

If you look at the documentation here: Tracker Stores, you can see that they have tablename: <name of the table to create, e.g. rasa> in the example. However, this will actually lead to a compilation error. Instead, table_name: <name of the table to create, e.g. rasa> is necessary for it compile correctly.

I used this feature recently without an issue. Can you provide more details on the problem you have run into? Do you have an example config and the error message you are receiving when you run Rasa?

Yes, my example config is

tracker_store:
  type: "dynamo"
  tablename: "mytable"
  region: "us-west-1"

where I got the following:

Experienced exception while trying to serve

TypeError: __init__() got an unexpected keyword argument 'tablename'

However, everything works fine (I’ve tested) with

tracker_store:
  type: "dynamo"
  table_name: "mytable"
  region: "us-west-1"

Note, I am using version 1.10.10
