API - PUT (Update) a Contact - Unable to create note

When using PUT (Update a Contact), and attempting to add a note, I get the error "The specified sub-resource 'note' was not found."  This is happening in both my app (Power Automate Flow) and on Constant Contact's API Tester.  Any assistance would be greatly appreciated.

 

Example Payload sent to the API Tester:

{
        "contact_id": "5f4697e6-3001-11ef-9cf5-fa163e72f71d",
        "update_source": "Contact",
"email_address": {

    "address": "[email protected]",
    "permission_to_send": "temp_hold",
    "opt_out_reason": "I am no longer interested in this service."

},
        "notes": [
            {
                "note_id": "b4b14c7f-b1b7-49fd-9075-2ed13fdf7cb2",
                "created_at": "2025-03-12T15:34:09.1983454Z",
                "content": "Note Body"
            }
        ]
    }

 

Returned Error:

[
{
"error_key": "contacts.api.bad_request",
"error_message": "The specified sub-resource 'note' was not found."
}
]
