Zapier -> Discord embed. error 400 invalid JSON

Question

I am trying to create a new custom request to post an embed from airtable to discord using Zapier custom request

It is setup exactly as per the other 2 working custom requests that currently generate embeds into my discord server. For some reason this one gives error 400 and i can't figure out why

    {
  "content": "",
  "embeds": [{
    "title": "__text in bold {{airtable data field}}__",
    "description": "*text in italics*",
       "color": 15856685,
    "footer": {
      "icon_url": "https://picture.com/picture.jpg",
      "text": "footer text"
    },
  "image": {
      "url": "{airtable url data feild}"
    },
    "author": {
      "name": "The Author",
      "url": "https://twitter.com/",
      "icon_url": "https://picture.com/picture1.jpg"
    },
    "fields": [
          {
        "name": "text",
        "value": "{airtable text field}"
      },
      {
        "name": "text",
        "value": "{airtable text feild}"
      },
      {
        "name": "url Links",
        "value": "[URL 1]({Airtable URL field})[URL 2]({Airtable URL field})",
"inline": true
              }
    ]
  }]
}
