Steps to reproduce or a small repository showing the problem:

When i update my typescript version to 2.7.1 my application’s build broken with the follow error:

PS C:\dsv\nest-api> npm run start:prod

nest-typescript-starter@1.0.0 prestart:prod C:\dsv\nest-api tsc

src/modules/common/services/base-data.service.ts(46,65): error TS2321: Excessive stack depth comparing types ‘T’ and ‘DeepPartial<T>’. src/modules/common/services/base-data.service.ts(67,65): error TS2345: Argument of type ‘T’ is not assignable to parameter of type ‘DeepPartial<T>’.

npm ERR! code ELIFECYCLE npm ERR! errno 2 npm ERR! nest-typescript-starter@1.0.0 prestart:prod: tsc npm ERR! Exit status 2

The service code is the follow:

export abstract class BaseDataService<T extends BaseModel> implements ICrudService<T>{

    constructor() {

    }
   
    ... other crud methods   

    public abstract getRepository(): Repository<T>;
    
    public async save(entity: T): Promise<T> {
        try {
            const response: T = await this.getRepository().save(entity);
            return response;
        } catch (error) {
            throw new BadGatewayException('ERROR.BASEDATASERVICE.SAVE');
        }
   }

}

Someone know why this is happening?

Can you guys please check it in the 0.2.15-rc.1 ? (npm i typeorm@0.2.15-rc.1)

Downgrading to 0.2.15-rc.1 did not fix the issue for me.
