Hi,
I’ve trying out the new session management in Rasa. I’m using Rasa v1.6.0. I overwrote the action_session_start in my actions to save one Slot but reset al the other slots. However, I’m noticing that after every message from the user, it’s running action_session_start and I think it may be resetting my slots prematurely.
I have the following configured in my domain.yml:
session_config:
session_expiration_time: 30
carry_over_slots_to_new_session: true
Here is an example (with names/messages hidden):

The section that I noticed was at 2020-01-14 15:58:28,949 the verify_UNIQUE_SLOTis set to True and ends the conversation but then at 2020-01-14 15:58:38,387, which is just 10 miliseconds later, when a new USER message comes in the verify_UNIQUE_SLOT is set to False. I’ve checked my slot verification and it appears to be okay, so I’m not sure why this is happening. This is causing the bot to go into a loop of continuously prompting the user for the same information over and over.
I’m also not sure why I keep seeing these two lines repeated at the start of every new message from the user:
2020-01-14 15:58:37,231 [DEBUG] The latest session for conversation ID 'USER' has expired.
2020-01-14 15:58:37,231 [DEBUG] Starting a new session for conversation ID 'USER'.
Shouldn’t the session only be reset after 30 minutes? I had tested it on a smaller example before and it was working so I’m surprised to see this happening.
Maybe I’m missing something?
Thanks
