How to properly type useFieldArray in a custom component?

[branislavbrincko]

I want to make a custom component that will use useFieldArray and will accept control and name for useFieldArray as props.

What I am struggling with is how to type fields - I want to make sure user passes form control, that has nameLocalizations field with { locale: 'en' | 'sk'; value: string }[] structure. So I did this:

TFieldValues extends {
    nameLocalizations: [
      { locale: 'en' | 'sk'; value: string },
    ]
  }

I expected the fields[0] to have locale and value fields, but this is not the case:

What am I doing wrong? How to make sure the fields is typed correctly? Thanks for any help
