last_owner

HTTP status: 409 · Code: last_owner

The action would leave an org without an owner.

Why it happens

The change would leave the org with no owner: removing the last owner, or changing the last owner’s role.

How to fix

Make another member an owner first, then make the change.

Catch it in your code

Every SDK throws one error type for a failed call. Match on its code, which is always last_owner for this error, never on the message.

JavaScript and Next.js

import { ErrorCode, OrvanoError } from '@orvano/js'

try {
  // your Orvano call
} catch (error) {
  if (error instanceof OrvanoError && error.code === ErrorCode.lastOwner) {
    // handle last_owner
  } else {
    throw error
  }
}

Dart and Flutter

import 'package:orvano_flutter/orvano_flutter.dart'; // or orvano_dart on a server

try {
  // your Orvano call
} on OrvanoException catch (error) {
  if (error.code != ErrorCode.lastOwner) rethrow;
  // handle last_owner
}

.NET

using Orvano;

try
{
    // your Orvano call
}
catch (OrvanoException error) when (error.Code == ErrorCode.LastOwner)
{
    // handle last_owner
}

The error also carries the HTTP status (409), a message, and a request ID. Quote the request ID when you report a problem: the server logs it with the failure. See Errors for how errors work in every SDK, or every error code.
