Type error creating new passkey getPasskeyDisplayName()

[kburkhart]

Looking for a little advice with an issue getting passkeys created.

On Laravel 12.18.0 / PHP 8.4.1, with the spatie/laravel-passkeys installed/configured following the instructions on spatie, when creating a new passkey from the /profile route, the following error is returned:

TypeError
App\Models\User::getPasskeyDisplayName(): Return value must be of type string, null returned
vendor/spatie/laravel-passkeys/src/Models/Concerns/InteractsWithPasskeys.php:29

Example liveware payload is:

    "_token": "RjdtYOiZ9w19cjdxlxeyyusKmB8RrdzAEwQCazPo",
    "components": [
        {
            "snapshot": "{\"data\":{\"name\":\"\"},\"memo\":{\"id\":\"DlRlQsxuZJJyi1e3ASgP\",\"name\":\"passkeys\",\"path\":\"profile\",\"method\":\"GET\",\"children\":[],\"scripts\":[\"1195062664-0\"],\"assets\":[],\"errors\":[],\"locale\":\"en\"},\"checksum\":\"31f499d8f4e10175de719c7fe44e493f57ed7f759ebf98659c5de68d10555d14\"}",
            "updates": {
                "name": "myPasskeyName"
            },
            "calls": [
                {
                    "path": "",
                    "method": "validatePasskeyProperties",
                    "params": []
                }
            ]
        }
    ]
}```

Hi,

I was having the same issue and bodged it by updating getPasskeyDisplayName() in src/Models/Concerns/InteractsWithPasskeys like this:

public function getPasskeyDisplayName(): string
    {
        return $this->name ?? 'Passkey';
    }

Hope this helps in the meantime

This isn't a bodge, this is what you need to do if your model doesn't have a "name" property, or if it is nullable.
