JSON output to html not right formatted but showing "

[rednas]

I am trying to read sensor data from Home Assistant with GET requests. I want to return the data using JSON.
I can get it to return:

{"result":"off"}

However, when I set the header content-type to application/json it shows:

{"result":"off"}

What am I doing wrong and how can I fix this?

Unfortunately, I dont know about Home Assistant but you could try escaping the quotes

e.g...

{\"result\":\"off\"}

Though i am certain there is a better way. Perhaps ask on the HA forum?

Yes, I also did. But it is occurring inside Node-RED.
This is what I do inside a function node:

var data={"result":msg.payload};
node.log(typeof data);
msg.payload=JSON.stringify(data);
//msg.payload=data;
return msg;

And subsequently I use a template node with:

{{payload}}

Formatted with "Mustache template" and Output As "Plain text".

This is equal for both with and without the json header specified.
So, I don't know why the difference is occurring...

And subsequently I use a template node with:

Ahh - thats the missing piece of the puzzle

Try {{{payload}}} in template instead of {{payload}}
