Custom block error "Unable to locate a class or view for component [filament-tiptap-editor::tools.batman]."

[khacnhat]

I follow the instructions to create a demo custom block, but I got the error:
Unable to locate a class or view for component [filament-tiptap-editor::tools.batman].
The step I did:

1. Create class BatmanBlock extends TiptapBlock
2. Create views resources/views/blocks/previews/batman.blade.php and resources/views/blocks/rendered/batman.blade.php
3. Register the block in AppServiceProvider.

Do I miss something?

Can you share the code or your block class? Seems like your namespaces might be off.
