FileUpload file validation after upload, before submit

Is it possible to validate a FileUpload field before submit? I can access the uploaded file using afterStateUpdated and similar functions, but is there any function other than rules that has access to $fail? I tried throwing ValidationError, etc but those didn't seem to work.

Solution:

Thanks! 💖 I may have gotten it working with

->afterStateUpdated(function (\Livewire\Component $livewire, Forms\Components\FileUpload $component) 
    $livewire->validateOnly($component->getStatePath())
})

->afterStateUpdated(function (\Livewire\Component $livewire, Forms\Components\FileUpload $component) 
    $livewire->validateOnly($component->getStatePath())
})

...
