SharePoint Form JSON Customize layout header - Managed metadata not working

I'm trying to add a managed metadata field titled Status to the header portion of a SharePoint form. 

Here is the JSON I am using:

{

  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/form-formatting.schema.json",

  "elmType": "div",

  "style": {

    "background-color": "#e8f5ee",

    "border": "1px solid rgba(0,0,0,0.1)",

    "border-radius": "8px",

    "padding": "12px 16px",

    "margin-bottom": "12px"

  },

  "children": [

    {

      "elmType": "div",

      "style": {

        "display": "grid",

        "grid-template-columns": "140px 1fr",

        "row-gap": "4px",

        "column-gap": "12px",

        "align-items": "center"

      },

      "children": [

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.2", "font-weight": "600", "color": "#616161", "font-size": "32px" }, "txtContent": "=[$Title]" },

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.35", "font-size": "18px" }, "txtContent": "='ID: ' + [$ID]"},

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.35", "font-size": "18px" }, "txtContent": "='Status: ' + [$Status]"},

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.35", "font-size": "18px" }, "txtContent": "='label: ' + [$Status.label]"},

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.35", "font-size": "18px" }, "txtContent": "='Label: ' + [$Status.Label]"},

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.35", "font-size": "18px" }, "txtContent": "='GUID: ' + [$Status.termGuid]"},

        { "elmType": "div", "style": { "margin": "0", "line-height": "1.35", "font-size": "18px" }, "txtContent": "='Path: ' + [$Status.path]"}

      ]

    }

  ]

}

Here is the result:

Only the Title and ID fields appear.  

All other attempts render blank.

The Status field does have a Value which I do see on the Body of the form

What is corret JSON syntax to display Managed metadata fields in the Header?
