Frigate Image (URL) to Android TV Notification Home assistant call service

Hi,
I want to get a notification with an image of a person standing near my front door on my android TV.
Background: I get the url of the image from the Frigate clips folder thru MQTT (Eventid) & want to push the image using Notify call service for Homeassitant.

Problem: I don't get the notification with the image .

Here is my sample flow:
image
Inject Node:
image

The flow:
[{"id":"2339d3b82b3174c4","type":"inject","z":"dd21e18ab46ee182","name":"","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"http://192.168.1.111:5000/clips/frontdoorcctv-1633953782.236539-1l7fv8.jpg","payloadType":"str","x":230,"y":640,"wires":[["ec9ce92e7edadcdb"]]},{"id":"ec9ce92e7edadcdb","type":"api-call-service","z":"dd21e18ab46ee182","name":"Notify","server":"406880bb.e9ed2","version":1,"debugenabled":false,"service_domain":"notify","service":"realme_tv_notify","entityId":"","data":"{\"message\":\"Someone at the Front Door.\",\"title\":\"Front Door BOT\",\"data\":{\"duration\":30,\"interrupt\":\"true\",\"fontsize\":\"small\",\"transparency\":\"0%\",\"color\":\"grey\",\"position\":\"bottom-right\",\"file\":{\"url\":\"{{msg.url}}\"}}}","dataType":"json","mergecontext":"","output_location":"","output_location_type":"none","mustacheAltTags":false,"x":390,"y":640,"wires":[[]]},{"id":"406880bb.e9ed2","type":"server","name":"Home Assistant","legacy":false,"addon":true,"rejectUnauthorizedCerts":true,"ha_boolean":"y|yes|true|on|home|open","connectionDelay":true,"cacheJson":true}]

Here is the data of notify Node(Call service):

{
    "message": "Someone at the Front Door.",
    "title": "Front Door BOT",
    "data": {
        "duration": 30,
        "interrupt": "true",
        "fontsize": "small",
        "transparency": "0%",
        "color": "grey",
        "position": "bottom-right",
        "file": {
            "url": "{{msg.url}}" //This msg.url is the payload from previous node or Inject node in above sample
        }
    }
}

The json editor only supports fully valid json. $$ is not valid.

Did you mean to use JSONata?
