'Request contains an invalid argument.' for messages send with Cloud Console

When sending a notification within the cloud console (with just a title and description).

I get this error:

Failed sending to target dqv6Wc40bEdfszpousRZwy:APA91bF8kIdBGMjB7Iqu22a1fEN_5lhsf05wY-510sQOV3YS8uvs7zwCM2NuKQgh7iDF15DPAYrq-osYEVaHBEQ1UqlxnOwg0C3Rv4x2SkTUebdE_XVVGkQ with error: Request contains an invalid argument.

What is also interesting is that the target is formatted with a '-' and ':' within the string. I am not sure if this is normal?

Some extra information:

• Initially the notifications work, after registering the token (For 1 or 2 messages)
• I validated that it happens on IOS (can't test on Android currently)

I register the token on device with the following method:

if (Platform.isIOS) { await FirebaseMessaging.instance.getAPNSToken(); }

final String? token = await FirebaseMessaging.instance.getToken();

if (token == null) {
  return null;
}

final String targetId = ID.unique();

  final Target target = await account.createPushTarget(
    targetId: targetId,
    identifier: token,
    providerId: 'xxxxxx',
  );

Which direction could I look into to debug this and is there a way to know what the invalid argument is?
