Problem with maria db post migration

After migration to mariadb external database

I have this error

2023-02-07 00:07:27.104 ERROR (Recorder) [homeassistant.components.recorder.util] Error executing query: (pymysql.err.IntegrityError) (1451, ‘Cannot delete or update a parent row: a foreign key constraint fails (homeassistant.statistics, CONSTRAINT statistics_ibfk_1 FOREIGN KEY (metadata_id) REFERENCES statistics_meta (id) ON DELETE CASCADE)’)
