Unable to trigger an intent (External Events)

Rasa Open Source

This topic is a continuation to Question about running External Events in Rasa X/Callback Input

Spec:

  • OS: Win 10
  • Python version: 3.8
  • Rasa version: 2.0.3

Hi, I was trying to make External Events work in my chatbot. I was doing everything as it was shown in https://rasa.com/docs/rasa/reaching-out-to-user/#external-events and https://github.com/RasaHQ/rasa/blob/master/examples/reminderbot/README.md. I think the problem must be with point 1 & 2 from this tutorial. I am not able to trigger an intent.

Here is how I was doing it:

  1. I’ve added to my chatbot NLU training data from the tutorial and updated domain.yml.
  2. I trained the model with rasa train.
  3. From reminderbot’s README.md: I ran rasa run actions and rasa x (I use Rasa X in local mode & I was also trying to open this with callback input as it was shown in the tutorial but it didn’t work too).
  4. After opening Rasa X I went into Talk to your bot and I copied ID conversation from there, then I opened another terminal to make post request. I was trying to 1) do this post request from the tutorial and 2) with post request from README.

In the first case, I got:

(env) PS E:\dev\project007\pro007> curl -H "Content-Type: application/json" -X POST -d \
Invoke-WebRequest : Cannot bind parameter 'Headers'. Cannot convert the "Content-Type: application/json" value of type "System.String" to type "System.Collecti 
ons.IDictionary".

After clicking on the above link I saw:

In the second case I got:

(env) PS E:\dev\project007\pro007> curl -X POST http://localhost:5005/webhooks/callback/webhook \

I will be grateful for help.

Hi, these error messages look like an issue with the commands themselves. Are you sure that these commands work on the Windows environment? Might be that curl requests look slightly different on that platform.

Thanks to @akelad

I run the post request from the tutorial via Git Bash instead of cmd or command prompt in VSC.
