Rasa Open Source

We are trying to send entities with a payload like

{"sender": "12345", "message": "/greet{'language': 'en'}"}

but the entities/slots are not getting set. Can you please help us with the same.

Endpoint : https://127.0.0.1:8443/webhooks/rest/webhook

Error:

/opt/venv/lib/python3.8/site-packages/rasa/shared/utils/io.py:99: UserWarning: **Failed to parse arguments in line '/greet{'language': 'en'}'. Failed to decode parameters as a json object (dict).** Make sure the intent is followed by a proper json object (dict). Continuing without entities.

JSON requires double quotes. Try this:

{"sender": "12345", "message": "/greet{\"language\": \"en\"}"}
