Я новичок в использовании Sequelize, я попытался создать валютную систему для разрабатываемой игры Discord Bot. Может быть, я делаю таблицы совершенно неправильно, но я думал, что этот метод будет работать для меня тоже. У меня есть еще несколько файлов, таких как dbInit. js, dbObjects. js, и в папке моделей у меня есть models / CurrencyShop. js, models / Users. js, models / UserItems. js если вам нужно увидеть что-то из этого, дайте мне знать.
Вот ошибки:
(node:5916) UnhandledPromiseRejectionWarning: SequelizeDatabaseError: SQLITE_ERROR: no such table: users
