Seeding a pivot table in heroku results to error

I'm deploying a Laravel 5.2 application with a database in Heroku. I've managed to migrate my tables without errors until it's time to seed the tables. The seeding always resulted in an error which is this:

Seeded: RolesTableSeeder
Seeded: PrivilegesTableSeeder

I've tried setting the $primary_key to null and one of the id columns in the pivot table but it always returns this error.
