Hi,

In my node-properties, I have defined the property as JSON object:

```auto
oneditprepare: function() {
            $("#node-input-subscribe").typedInput({
                type:"json",
                types:["json"]
            });
        }

```

This is how I define in HTML:

```
    <label for="node-input-subscribe"><i class="fa fa-spinner"></i>&nbsp;Subscribe</label>
    <input type="text" id="node-input-subscribe">

```

Then I get the input value in my `node.js` file as:

```auto

RED.nodes.createNode(this,config);
        node.config = config;
        node.subscribe = config.subscribe;

```

However when I send `node.subscribe` to Node-RED what I get is `string` not an object. I am checking via `debug `node:

```auto
msg : string[8]
"{"service":1453}"

```

What I am missing here?

Edit: Now I see, in the [docs](https://nodered.org/docs/api/ui/typedInput/#options-types), it is mentioned as

> a valid JSON string

So it is not converted, it is a JSON string by default. So, is there any way to get object?

You will have to run JSON.parse(string) to convert it to an object. Be warned, JSON.parse can throw an error if the string cannot be parsed and that could crash node-red. You might want to wrap it in a try - catch block.

Thanks @kevinGodell, this is what I am doing right now. That means there is no way to send object right?

Run the JSON.parse() inside your node before sending it.
