Vue Failed to resolve component n

i'm trying to clean my console from all the Vue Warnings. This one comes to be a real pain. I don't know where to look. Does anyone can point me into the right direction?

I'm using Vue3 with cdn and the structure is:

GrandParentComponent
      ----  Parent Component
            -----  ChildComponent

I'm listening to and event form the child component with $emit(event, {data1: 'data1' data2:'data2'} and handling it on the parent component.
