Type 'UnpackedIntersectionWithNull<HydratedDocument<T, {}, {}>, {}>' is not assignable to type 'T'.

Hi again,

for some reason I got the following error that comes from the MongoGenericRepository.

Here's the mongo generic repo:

import { Model } from 'mongoose';
import { IGenericRepository } from 'src/core/abstracts/generic-repository.abstract';

export class MongoGenericRepository<T> implements IGenericRepository<T> {
  private _repository: Model<T>;
  private _populateOnFind: string[];

  constructor(repository: Model<T>, populateOnFind: string[] = []) {
    this._repository = repository;
    this._populateOnFind = populateOnFind;
  }

  getAll(): Promise<T[]> {
    return this._repository.find().populate(this._populateOnFind).exec();
  }

  get(id: any): Promise<T> {
    return this._repository.findById(id).populate(this._populateOnFind).exec();
  }

  create(item: T): Promise<T> {
    return this._repository.create(item);
  }

  update(id: string, item: T) {
    return this._repository.findByIdAndUpdate(id, item);
  }
}

The error is in the get method, here's the whole traceback:

src/infrastructure/data-services/mongo/mongo-generic.repository.ts:18:5 - error TS2322: Type 'Promise<UnpackedIntersectionWithNull<HydratedDocument<T, {}, {}>, {}>>' is not assignable to type 'Promise<T>'.
  Type 'UnpackedIntersectionWithNull<HydratedDocument<T, {}, {}>, {}>' is not assignable to type 'T'.
    'T' could be instantiated with an arbitrary type which could be unrelated to 'UnpackedIntersectionWithNull<HydratedDocument<T, {}, {}>, {}>'.

return this._repository.findById(id).populate(this._populateOnFind).exec();

For some reason I don't get it in your code but it arises in mine but the code is identical. Any ideas?

@icodefish how did you resolve this?
