Typescript error: TS2611: 'queryRunner' is defined as a property in class 'EntityManager', but is overridden here in 'MongoEntityManager' as an accessor.

Projects using typeorm@0.2.27 fail to build due to an error:

node_modules/typeorm/entity-manager/MongoEntityManager.d.ts:27:9 - error TS2611: 'queryRunner' is defined as a property in class 'EntityManager', but is overridden here in 'MongoEntityManager' as an accessor.

27     get queryRunner(): MongoQueryRunner;
           ~~~~~~~~~~~

This is fixed my reverting to 0.2.26

We aren't using typescript 4.0 yet - does it work with typescript 3.9?

I tested 0.2.27 on typescript 3.9 and it works for me.

[imnotjames]

That's a bummer. Is there a configuration option we can be using to prevent that? Or is it just a limitation that's imposed in 4.0 that's not in 3.9?

Is 4.0 backwards compatible?

I think this is a duplicate of #6805

[imnotjames]

I'll be closing this issue in favor of #6805 - please continue the discussion there

Cheers
