FormAction recognized but not launched in HTTP API call

Hi Everyone,

I managed to link my RASA bot to Postman using the API.

I run my actions using:

rasa run actions

And I run rasa using:

rasa run -m models --enable-api --log-file out.log --debug

The problem is that when I start a conversation by adding a message to the tracker, the greetings intent is perfectly captured, the next action (in my case is to activate the form after a greeting) is also perfectly predicted but the followup_action is null and when I check the conversation status I get this at the end:

"latest_input_channel": null,
"active_form": {},
"latest_action_name": "action_listen"

This is how I injected a message to the conversation: http://localhost:5005/conversations/{conversation_id}/messages Body: {“text”: “hello”, “sender”: “user”}

Thanks in advance for your returns !
