PATCH error.

[MrSerWin]

the same problem but issue is closed, thats why I desided open new one.
I have an error on PATCH operation.

I'm using the latest version from CDN
https://cdn.jsdelivr.net/npm/fhirclient@latest/build/fhir-client.min.js
My request is :
const url = /Patient/PatientID; // I use correct ID patient there
const response = await fhirClient.patch(url, body)
where body is:

 [
    {
        "op": "add",
        "path": "/gender",
        "value": "male"
    },
    {
        "op": "add",
        "path": "/name",
        "value": [
            {
                "family": "Abbott1",
                "given": [
                    "Geoffrey1"
                ]
            }
        ]
    },
    {
        "op": "add",
        "path": "/birthDate",
        "value": "1990-09-01"
    }
]

response is:

{
    "resourceType": "OperationOutcome",
    "text": {
        "status": "generated",
        "div": "<div xmlns=\"http://www.w3.org/1999/xhtml\"><h1>Operation Outcome</h1><table border=\"0\"><tr><td style=\"font-weight: bold;\">ERROR</td><td>[]</td><td><pre>Failed to call access method: java.lang.NullPointerException: input cannot be null</pre></td>\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t</tr>\n\t\t</table>\n\t</div>"
    },
    "issue": [
