Typeorm not compiling with Typescript 3.6.2 - "Excessive stack depth"

Issue type:

[ ] question [x] bug report [ ] feature request [ ] documentation issue

Database system/driver:

[ ] cordova [x] mongodb [ ] mssql [ ] mysql / mariadb [ ] oracle [ ] postgres [ ] cockroachdb [ ] sqlite [ ] sqljs [ ] react-native [ ] expo

TypeORM version:

[ ] latest [ ] @next [x] ^0.2.18 (or put your version here)

Steps to reproduce or a small repository showing the problem:

• Try to build a project containing typeorm (version 0.2.18 in my case) with the newest typescript version (I used Typescript 3.6.2)
• Get an error message looking like:

Error TS2321: Excessive stack depth comparing types 'MongoRepository<Entity>' and 'Repository<Entity>'.

[redacted]/api/node_modules/typeorm/repository/MongoRepository.d.ts(12,22): error TS2589: Type instantiation is excessively deep and possibly infinite.

[redacted]/api/node_modules/typeorm/repository/MongoRepository.d.ts(45,5): error TS2321: Excessive stack depth comparing types '(optionsOrConditions?: string | number | Date | ObjectID | FindOneOptions<Entity> | Partial<Entity>, maybeOptions?: FindOneOptions<Entity>) => Promise<Entity>' and '{ (id?: string | number | Date | ObjectID, options?: FindOneOptions<Entity>): Promise<Entity>; (options?: FindOneOptions<Entity>): Promise<Entity>; (conditions?: FindConditions<Entity>, options?: FindOneOptions<...>): Promise<...>; }'.

Temporary workaround

Rollback to Typescript 3.5.3, then compiling works again.

EDIT Sept. 16, 2019: A fix has been deployed, see https://github.com/typeorm/typeorm/issues/4681#issuecomment-531512317

This was solved in the latest TypeORM version 0.2.19. Working with typescript 3.6.3.

Looks like issue was resolved some time ago.
