This should be translatable.

What about the case when the source gets registered only on the server? It's all custom sources these days because the client-side API is still private. @SantosGuillamot and I were discussing exposing the registered sources from the server in a different PR

@gziolo I don't follow 🤔 Sources that get registered on the server using register_block_bindings_source() need to provide a label, which is what we would use here. The error would only arise when users try to bind a block to a source and mistype the source's name, or if they attempt to connect to a source that hasn't been registered. And as far as I see, the panel would get rendered regardless of what kind of block it is, core or custom, as long as it has the metadata.bindings property (though this should probably be tested — will take a look at that).

To clarify, what are you referring to when you say "client-side API", and how does it relate to this scenario?

The sources we are consuming in the editor need to be registered in JS as well. They provide functions to know how to get the values and how to update them in the editor. One example could be the post-meta source that is registered here.

Registering in the client is not mandatory, and it doesn't mean it won't work on the server. So it is not exactly an error. I believe right now we are using "Dynamic Data" as a generic message, but we could also fallback to the key maybe.

In the future, as Greg mentions, we would like to reuse the server registration somehow, but that will be handled in a separate PR.

Ok got it! Thanks so much for the explanation, that's very helpful 😄
I can revise to use the name in the binding when a label isn't present 👍

Update: I've replaced the error with the machine-readable name.
