UPDATE :
I started to seed the first ones (by 5 or 6) by commenting the rest, then commenting what I seeded and uncommenting the next ones, and it worked. At some point, I got the error again, and I seeded one instead of 5 or 6, it worked. Then the next one gave me another error :
SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'field list' (SQL: insert into `resultats` (`annee`, `resultat`, `0`, `bureaux_depouilles`, `election_liste_zone_id`, `maj`, `nb_bureaux`, `previous_data`, `validation`) values (2018, 24, 50, 3, 197, 2018-10-15 10:58:54, 3, 3, 0))
