JsonParseException: unable to parse utc timestamp

Ignition

Is there something wrong with my timestamp that I'm not seeing?
This is the full resource.json in case it matters:

{
  "scope": "G",
  "version": 2,
  "restricted": false,
  "overridable": true,
  "files": [
    "style.json"
  ],
  "attributes": {
    "lastModification": {
      "actor": "pyro-resource-signature",
      "timestamp": "2024-01-05T02:14:10.53Z"
    },
    "lastModificationSignature": "7e0bf1c8c02ac9bdf9446c3942e9adbb0ec4d16470ee092b9b825edb38d826da"
  }
}

Must be the milliseconds.

This is the parser it uses:

    private static final DateFormat ISO_8601_UTC_DATE_FORMAT;

    static {
        ISO_8601_UTC_DATE_FORMAT = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
        ISO_8601_UTC_DATE_FORMAT.setTimeZone(TimeZone.getTimeZone("UTC"));
    }
