Alexa Skill: Interaction model is not being updated during test - aws-lambda

Question

I am developing a Alexa Skill and I have an Intent named NewAppointmentIntent which originally had 7 slots.
I have added a new Slot yesterday named Doctor and successfully built the Skill.
When I invoke that intent, it still have 7 Slots and not 8. The Doctor Slot does not appears in the request and responses outputs.
The Intent in images:
The output when invocing the Intent, where slot Doctor expected in slots attribute:
"request": {

}
}
},

So I wish to know how to refresh the Skill?

Answer 1

Close the window, re-open and in your console -> Save the model -> Build the model. Then test again.
If still doesn't show, click on the JSON Editor(this will be the last option in the list of your Interaction model), then in your NewAppointmentIntent can you see the Docter slot in the slots array?
If not, then maybe something was broken when you created the slot. So delete the Docter slot and re-add it. Then again verify it in JSON editor and this should solve the problem.
