Worker A binding to Worker B leads to `403` error upon runtime fetch call. Why?

I have two works, A & B, A binds to B. When A does the env.BINDING.fetch(...) call it leads to a 403 response. That response is NOT coming from our code. Why is CF doing this? The body response is: error code: 1003

Never mind, I wasn't calling correctly the fetch from the binding. ☑️
