Actions can not be triggered

Hi, everyone, I encounter a problem that all the actions in my story cannot be triggered.

Firstly, I use

rasa init

to create all of my files,

then, I uncomment the hello world action:

then, I write this action to domain file, and write the action into story:

finally, I use

rasa train

to train my model.

I open two terminals, execute

rasa shell and rasa run actions separately,

when I send greet intent, nothing happens, my hello world action is just not triggered.

I want to ask what happened, and how can I fix it. I have tried different rasa versions which are 2.2 and 2.1.3. my actions can work well in rasa 1.0+

Wish you can help me, thank you!

Hi @ForLittleBeauty, have you uncommented the action_endpoint section in endpoints.yml? If not, add the below two lines and run again…

  url: "http://localhost:5055/webhook"
