Current behavior

I'm making a project for a cryptobank, but I dont know how to pass this part. I already tried a lot of things and searched for help, but didnt find it. follow my userservice

 async cryptoTransfer(TransactionsDto: TransactionsDto, Id: string, @Request() req) {
    const queryRunner = this.DataSource.createQueryRunner();

    await queryRunner.connect();
    await queryRunner.startTransaction();

    try {
      let fromUser = await this.repository.findOne({where: {Id}})
      let toUser = await this.repository.findOne({where: {Id}})
      let quantityTransfered = req.body.quantityTransfered

      fromUser.CryptoWallet -= quantityTransfered;
      toUser.CryptoWallet += quantityTransfered;

      await queryRunner.manager.save(fromUser);
      await queryRunner.manager.save(toUser);

      await queryRunner.commitTransaction();

    } catch (error) {
      await queryRunner.rollbackTransaction();
      throw new InternalServerErrorException();
    } finally {
      await queryRunner.release();
    }
  }

here, the transactionDto

import { UserEntity } from 'src/user/entities/user.entity';
import {ApiProperty} from '@nestjs/swagger';
import {IsNotEmpty} from 'class-validator';

export class TransactionsDto {
  @ApiProperty()
  @IsNotEmpty()
  fromUser: UserEntity;

  @ApiProperty()
  @IsNotEmpty()
  toUser: UserEntity;

  @ApiProperty()
  @IsNotEmpty()
  quantityTransfered: number
}
