After implementing slugify hook, I got an error, when refreshing my database, from the seeders. I use sqlite for database. The refresh and start_seeder passed well, but not the fake_seeder, and I get : Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call? as error.
To fix it (after searching), I added pool: {min: 0, max: 30, idleTimeoutMillis: 600000,} in config/database.ts, just after client: 'better-sqlite3', probably not the best solution.
