Problem in invoking HTTP API to execute action from Postman app

Rasa Open Source
1

I am trying to execute an action using HTTP API from the Postman app. I am storing my tracker using the PostgreSQL tracker store.

Rasa version used: 1.1.8

POST API: http://127.0.0.1:5005/conversations/myid/execute

Header: Content-Type=“application/json”

JSON body:  {
  "name": "action_http"
}

I get the following error in terminal, while invoking execute action POST api from Postman app:

2019-11-18 11:10:28 DEBUG    rasa.core.actions.action  - Calling action endpoint to run action 'action_http'.
2019-11-18 11:10:29 ERROR    rasa.core.processor  - Encountered an exception while running action 'action_http'. Bot will continue, but the actions events ar
e lost. Please check the logs of your action server for more information.

BTW this works fine when I try to invoke this HTTP API from javascript. Has anyone ever faced such issue?
