type-graphql update mutation with typegoose

[Sed9yDataBank]

Hello,
I am trying to update my document using typegoose and type-graphql.
The Problem: but it's returning the old document in graphql playground, even in the mongo database there is no sign for the updates I made.

@Mutation(() => Position, { nullable: true })
  async updatePosition(
    @Arg("positionId", type => ObjectIdScalar) positionId: ObjectId,
    @Arg("position", () => PositionInput, { nullable: true }) positionInput: PositionInput
  ): Promise<Position | null> {
    const position = await PositionModel.findById(positionId);
    if (!position) {
      return null;
    }
    if (typeof positionInput !== "undefined") {
      await PositionModel.updateOne({ positionId }, { ...positionInput }, { returnOriginal: false });
    }
    return position;
  }

@InputType()
export class PositionInput implements Partial<Position> {
  @Field()
  positionName!: string;

  @Field({ nullable: true })
  positionOfficeLocation?: string;

  @Field({ nullable: true })
  positionDepartment?: string;

  @Field({ nullable: false })
  positionTotalNeeded!: number;

  @Field({ nullable: false })
  positionStatus!: string;

  @Field(() => [ProgressionInput])
  progressions: ProgressionInput[];

  @Field(() => [CandidateInput])
  candidates: CandidateInput[];
}

Output in graphql playground:

I don't know how this is a problem with TypeGraphQL.

const position = await PositionModel.findById(positionId);
return position;

That's why you receive old document. You return it. Read again from database after updating to return updated document.

Tried that and did not work, unfortunately.
I was just looking at the typegoose example in the repo since I am pretty new to using this and have not found a update mutation example there.

After multiple attempts I got it working:

@Mutation(() => Boolean, { nullable: false })
    async updatePosition(
      @Arg("positionId", type => ObjectIdScalar) positionId: ObjectId,
      @Arg("position", () => PositionInput, { nullable: true }) positionInput: PositionInput
      ) {
        
        const position = await PositionModel.findOneAndUpdate({
            _id: positionId as any
        }, positionInput);

        if (position)
           return true;
        else return false;
    }

I have not changed anything in the PositionInput.
Thank you for your time @MichalLytek !

@Mutation(() => Boolean, { nullable: false })
async updatePosition(
  @Arg("positionId", type => ObjectIdScalar) positionId: ObjectId,
  @Arg("position", () => PositionInput, { nullable: true }) positionInput: PositionInput
  ) {
    return await PositionModel.findOneAndUpdate({
        _id: positionId as any
    }, positionInput);
}

You could tidy up this with the above.
