Bei der Migration tauchen bei Bestellungen ein paar Fehler wie diese auf:

```auto
[error] SWAG_MIGRATION_RUN_EXCEPTION
An exception occurred
Entity: order, sourceId: 63770
Warning: Trying to access array offset on value of type null

```

Frage, wo nach muss ich suchen um den Fehler zu beseitigen?
