The problem can probably be seen in the blade not in the LiveWire Model. In most cases this error tells you you did not wire:key all necessary places.

Each <livewire:xxx Give it a unique wire:key="UNIQUE_SOMETHING"

Each foreach loop inside a livewire blade file that contains livewire structures... first element, like a div. Give it a wire:key="UNIQUE_SOMETHING"

If you do that you very likely get rid of this problem. I ran into that issue (foreach case) when updating to livewire 3 a lot.

@anikett I have the same issue where it works fine on my dev environments but when pushed to the server I get the "Uncaught Snapshot missing on Livewire component with id: R1rsgkBVrClAl8P8eYzL" error.

I have assigned wire:key to each livewire component and not using any loops.

Did you figure it out?
