Intent json not accepted by home assitant

I’m trying to integrate rhasspy with home assistant.
I’ve achieved to switch on/off devices in home-assistant with postman using the API from Home Assistant (/api/intent/handle)
And setting the JSON body like this:
{ “name”: “ChangeRobotState” }

But I’m not able to do the same from rhasspy. I suspect the json is not correct.

Because when taken the json from rhasspy and added it to postman it answers the following.

Message format incorrect: extra keys not allowed @ data['entities']

Any tip or help will be much appreciated!
