Serial number is invalid

[SamMousa]

When attempting to register a new authenticator using bna new the given serial is not valid:

I've retried several times. The response from blizzard (export from dev tools):

{
    "timestamp": 1644569040108,

    "error": "None",

                "Pattern"
            ],
            "arguments": [
                {

                        "serialNumber"
                    ],
                    "arguments": null,
                    "defaultMessage": "serialNumber",
                    "code": "serialNumber"
                },
                [],
                {
                    "arguments": null,
                    "defaultMessage": "[A-Za-z0-9]{3,128}",
                    "codes": [
                        "[A-Za-z0-9]{3,128}"
                    ]
                }
            ],
            "defaultMessage": "error.authenticator.invalidSerial",
            "objectName": "attachAuthenticatorCommand",
            "field": "serialNumber",
            "rejectedValue": "EU-2202-1199-4827",
            "bindingFailure": false,
            "code": "Pattern"
        }
    ]
}

Reading the error more closely led me to try entering the serial number without dashes; this worked!
