Type 'Entity' does not satisfy the constraint 'ObjectLiteral'. update(): UpdateQueryBuilder<Entity>;

Expected Behavior

Just Build without any error.

Issue Description

Build Time error. It Work perfectly in development. When run build (tsc -p .) then getting this error below.

We are using version 0.2.45 and are faced with the same issue. It is difficult for us to migrate to typeorm 0.3 at this time and we would like to use the latest TS version. Is it possible to come up with a patch for typeorm 0.2? Here is the error we are seeing:

Maybe https://devblogs.microsoft.com/typescript/announcing-typescript-4-8/#unconstrained-generics-no-longer-assignable-to is relevant to explain this issue.

Let me add a minimun example of my issue:

import { Repository } from 'typeorm';

interface RepositoryWrapper<T> {
  repository: Repository<T>
}

Consider ts playground references:

• typescript@4.7.4
• typescript@4.8.2

As metioned in TS 4.8 release notes linked above, T is no longer assignable to {} so it’s no longer valid in ts 4.8.X because T no longer constraints ObjectLiteral.

Having said that, just to know, why typeorm’s Repository, QueryBuilder… are enforcing Entity to extend ObjectLiteral?

./node_modules/typeorm/repository/Repository.d.ts

export declare class Repository<Entity extends ObjectLiteral> {
// ...
}

Having a look at ObjectLiteral:

./node_modules/typeorm/common/ObjectLiteral.d.ts

/**
 * Interface of the simple literal object with any string keys.
 */
export interface ObjectLiteral {
    [key: string]: any;
}

It seems this constraint is the cause of the issue, do we have a reason for keeping it?
