$firstName error in user DTO

[thisisandreww]

Hi there, I'd like to report an issue that we face when we're using this library in one of the webhook handling events. This error message showed up for one of the groups that trigger the webhook.

Cannot assign null to property DefStudio\Telegraph\DTO\User::$firstName of type string {"exception":"[object] (TypeError(code: 0): Cannot assign null to property DefStudio\Telegraph\DTO\User::$firstName of type string at /vendor/defstudio/telegraph/src/DTO/User.php:31)

Does anyone have an idea on this?
