Using Docker for dev  
Version 4.0.0-18

I'm creating a custom node and using an optional JSON input in the edit dialogue.

These values can be entered in the config or passed in the msg object.

```auto
tags: {value:'',required:false},

```

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

```

```auto
<div class="form-row node-input-tags">
        <label for="node-input-tags"><i class="fa fa-tag"></i> XMP Tags</label>
        <input type="text" id="node-input-tags" placeholder="">
</div>

```

If I edit the node configuration, I get a red ring around the input as if it's required.

If I leave it blank and save, I get the red triangle, and I can deploy even though I get the misconfiguration warning.

The node works as expected, even with the red triangle warning.  
If I refresh the editor, the triangle will disappear until I edit the node configuration again.

The issue does not affect functionality; the node and the flow work as expected.  
Just annoying and will have users puzzled.

Can you raise an issue on GitHub? The fact you have `required` set to false means the validation should allow a blank string I think.

Ok, TypedInput returns false because required skip the false option. Will fix that
