Walkthrough

The change modifies TagNameFunc in validator.go to return the actual struct field name when a JSON tag is empty, instead of returning an empty string. This adjusts error reporting behavior for fields without explicit JSON tags.

23-25: LGTM! Sensible fallback for better error messages.

This correctly handles the case where a struct field has no JSON tag (or uses json:",omitempty" without an explicit name), ensuring validation errors always reference a meaningful field identifier instead of an empty string.
