# X_PERSONAL_DATA_UNREACHED

## Means

an entity carries personalData() columns no declared subject reaches

## Typical cause

no defineSubject() walk reaches the entity, so neither an export nor an erase would ever see its marked columns

## Fix

`defineSubject(<entity>, { … })` — in the module declaring the subject: a subject of its own, or a reference / columns: entry so an existing subject reaches it
