I have this json data:

{
   "guid": "73895342-7822-4871-b46c-0b345d89a3ac",
   "message": "Hhhjj
        <div style="background-color:#000000;border-radius:20px;webkit-border-radius: 20px;-moz-border-radius: 20px;padding:0;margin:0;"><iframe style="padding:0;margin:0;border-radius:10px;width:100%;height:200px;" src="https://www.youtube.com/embed/75fDo2yk6RM" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div>
        Vbbbbf

        <div style="background-color:#000000;border-radius:20px;webkit-border-radius: 20px;-moz-border-radius: 20px;padding:0;margin:0;"><iframe style="padding:0;margin:0;border-radius:10px;width:100%;height:200px;" src="https://www.youtube.com/embed/75fDo2yk6RM" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div>",
   "messagePlain": "Hhhjj
        

        Vbbbbf

        https://youtu.be/75fDo2yk6RM?si=QxkLmcT_TiIgHiTf",
   "messageId": 0,
   "messageUpdateId": 1444
}

I have added the escape character but still get this error:

"'0x0A' is invalid within a JSON string. The string should be correctly escaped. Path: $.message | LineNumber: 2 | BytePositionInLine: 19."

can someone see what I am missing?
