nsert data after migration make errors using prismaClient

Question

I have a problem that I can't solve. I have this model:

model PermisConduire {
    id             Int     @default(autoincrement()) @id
    noPermis       String   @map("no_permis") @db.VarChar(50)
    dateExpiration DateTime @map("date_expiration") @db.Timestamp(6)
    
    Chauffeur Chauffeur? @relation("permisConduire_chauffeur")
    @@map("permis_conduire")
}

when I migrate the data in my database and then I fill it with an npx prisma db seed, when adding new users with prismaClient using prisma.permisConduire.create() I get the following error on my unique identifier:

return await this.prisma.permisConduire.create

Unique constraint failed on the fields: (id)

On the other hand, when I do a migration in my database without doing any seed to add data to my database during the migration, I have no error in my addition of data with prismaClient and the command prisma.permisConduire.create()

I don't understand why it behaves like this, can you help me?

thank you all for your answers
