Hi everyone,
Recently we have a problem with our formactions. This problem seems to appear in all forms and we have tried it out on the “good mood” bot of the build-in rasa example. We added a small form here and the problem appears as well.
Problem description: Form execution rejected if slot is not extracted. (TED policy takes over)
Assumed behavior: Form repeats asking for slot.

config.yml/credential.yml/endpoints.yml stay default
Output: If the entities are given correctly in the dialog, everything goes fine (formaction gets activated, rulepolicy gets us through the form and the form gets deactivated correctly)
If the entities are missing in the user input (for example saying hello instead of giving the weekday) the following output is generated:
Which weekday is it?
Your input -> hello
rasa.core.processor - Received user message 'hello' with intent '{'id': 286870438279032377, 'name': 'greet', 'confidence': 0.9999989867210388}' and entities '[]'

rasa.core.policies.ensemble - Execution of 'test_form' was rejected. Setting its confidence to 0.0 in all predictions.
rasa.core.policies.ensemble - Made prediction using user intent.

rasa.core.policies.ensemble - Predicted next action using policy_1_TEDPolicy.

Most likely there is a misunderstanding on our side but shouldn’t this input lead to repeated question “Which weekday is it?”
Thank you in advance! Your help is appreciated
First one (happy path) same as you did above (works fine):
