Add comment and Do Transitions via rest api v3

[Rajesh Ale]

{
"update": {
"comment": [
{
"add": {
"body": "Requesting support from HelpDesk."
}
}
]
},
"transition": {
"id": "71"
}
}

Above request works with rest api v2, any idea how to make it work for v3  . getting this error for v3

{
    “errorMessages”: [],
    “errors”: {
        “comment”: “Operation value must be an Atlassian Document (see the Atlassian Document Format)”
    }
}
