Steps to reproduce or a small repository showing the problem:

I am using nestjs, I have defined an enum in an entity and used there. I needed to use it also in another entity, however, using an import typeorm seems to not resolve it.

In my file order.entity.ts I define

export enum OrderStatus {
    placed = "placed",
    paid = "paid",
    confirmed = "confirmed",
    shipped = "shipped",
    completed = "completed",
    cancelled = "cancelled"
}

@Entity()
export class Order extends BaseEntity {
    @PrimaryGeneratedColumn("uuid")
    id: string

    @IsNotEmpty()
    @Column({ type: "enum", enum: OrderStatus })
    status: OrderStatus
}

and in the issue entity order-product.entity.ts I write:

import { OrderStatus } from "./order.entity";

@Entity()
export class OrderProduct extends BaseEntity {
    @PrimaryGeneratedColumn("increment")
    id: number

    @IsNotEmpty()
    @Column({ type: "enum", enum: OrderStatus })
    status: OrderStatus
}

The resulting query is CREATE TABLE `order_product` (`id` int NOT NULL AUTO_INCREMENT, `status` enum NOT NULL, PRIMARY KEY (`id`)) producing an sql error as the enum is not defined.
The error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NOT NULL, PRIMARY KEY (`id`))' at line 1

Defining the enum also inside the orderProduct entity file the enum is resolved and the query is executed correctly.
