L'opération n'a pas pu être terminée, probablement à la suite d'une :
- suppression : vous avez essayer de supprimer un enregistrement auquel d'autres enregistrements font référence
- création/modification : un champ requis n'a pas été correctement rempli

The error message (in french) is about a problem of FK. note that the product is reported as created on 1st line of the log.
