How to update notificationTokens by calling API?

Hello, i want to update the notificationsToken by my generated token on my app on IONIC, but i try to make the call to the API from Postman and the response is:

Unrecognized field "notificationTokens" (class org.traccar.model.User), not marked as ignorable (26 known properties: "readonly", "limitCommands", "deviceLimit", "poiLayer", "fixedEmail", "login", "name", "latitude", "administrator", "phone", "longitude", "userLimit", "temporary", "zoom", "twelveHourFormat", "attributes", "deviceReadonly", "id", "email", "totpKey", "coordinateFormat", "disableReports", "password", "map", "disabled", "expirationTime"])
 at [Source: (org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream); line: 2, column: 28] (through reference chain: org.traccar.model.User["notificationTokens"])

The authorization is Basic Auth with my credentials, the URL is https://www.mytraccarurl.com/api/users/1
The ID and the Basic Auth are the same. And the body on raw JSON

{
    "notificationTokens": "example"
}

There is a URL that makes the update for notificationsTokens?

Update:
I saw that the notificationTokens are on attributes on the user, but when i make the same call with Postman in PUT mode.

{
    "attributes": {
        "notificationTokens": "example"
    }
}

I just get

Cannot invoke "org.traccar.model.User.getAdministrator()" because "before" is null - NullPointerException (PermissionsService: 179 < BaseObjectResource: 95 < ... < OverrideFilter: 49 < ...)

You have to send the whole model. We don't support any patch API.

{"id":1,"attributes":{"activeMapStyles":"custom","notificationTokens":""},"name":"XXXXXXXXXXXXX","login":null,"email":"adminmail@gmail.com"
,"phone":null,"readonly":false,"administrator":true,"map":null,"latitude":0.0,"longitude":0.0,"zoom":0,"twelveHourFormat":false,
"coordinateFormat":null,"disabled":false,"expirationTime":null,"deviceLimit":-1,
"userLimit":0,"deviceReadonly":false,"limitCommands":false,"disableReports":false,"fixedEmail":false,
"poiLayer":null,"totpKey":null,"temporary":false,"password":null}

That's what i got on all the model when i navigate to https://www.mytraccarurl.com/api/users/1
