Synchronize promise based migration

The notification always appears “Migrations: Finished migrating.” before the real migration seed is finished. I chained all. I’ve checked all.
During migration, we use the async mechanism

const { db } = MongoInternals.defaultRemoteCollectionDriver().mongo;

        const updated = Promise.await(
