I saw this phrase when I was trying to modify the field of a particular record and it seems to be because the record it was looking up was deleted.
This field's what to do if the lookup record is deleted is set to clear the value of this field, but this is what happened during the migration process.
When a record that a particular record was looking up was deleted and it became impossible to delete or modify it, how to resolve it.

Hello @lee sihyeon if you delete a parent record, lookup fields pointing to this record should become empty/null. If you keep a "zombie" lookup field, please make sure the initial record has been hard deleted, and if you keep on getting errors, make a dedicated specific database action to clean other records' lookup fields so that you make sure you will gonna be able to modify these records in the future without worrying for the lookup-related error.
