NestJS: TypeError: Cannot read property 'find' of undefined

I heard about NestJS and really wanted to try it out. I followed a basic getting started and ended up in the following error for custom repository instantiation.

TypeError: Cannot read property 'find' of undefined#

After some search, I found a solution in nestjs/typeorm issues.

Fix#

Do not provide the custom repository in the providers array of NestJS module. TypeORM does its own thing.

After removing the repository from the providers array, it worked fine. ^_^
