Как исправить ошибку Cannot read properties of undefined (reading 'securityService')?

Question

[dossayevd]

Я пытаюсь сделать POST запрос и получаю эту ошибку:

{
"msg": "Cannot read properties of undefined (reading 'securityService')"
}

Кроме того, когда я пытаюсь выполнить console.log(this.securityService), и получаю такую же ошибку.

security.controller:

/* eslint-disable no-console */
import { IRouter, Request, Response } from 'express';
import { StatusCodes } from 'http-status-codes';
import SecurityService from './security.service';

class SecurityController {
  private securityService: SecurityService;

  constructor(private router: IRouter) {
    this.router = router;
    this.securityService = new SecurityService();
  }

  public async sendVerificationCode(req: Request, res: Response) {
    try {
      console.log(this.securityService);

      const { receiver } = req.query;
      const user = await this.securityService.getUser(String(receiver));

      console.log(user);

      if (!user) {
        return res.status(StatusCodes.CONFLICT).json({ msg: "User with this phone number doesn't exist" });
      }

      const id = await this.securityService.sendSms;

      return res.status(StatusCodes.OK).json({ id });
    } catch (error) {
      return res.status(StatusCodes.INTERNAL_SERVER_ERROR).json({ msg: error.message });
    }
  }
}

export default SecurityController;

security.service:

/* eslint-disable no-console */
import { getRepository } from 'typeorm';
import VerificationEntity from '../entities/verification.entity';

class SecurityService {
  public async getUser(receiver: string) {
    console.log('Check 2');
    return getRepository(VerificationEntity).findOne({ mobilePhone: receiver });
  }

  public async sendSms(body: { receiver: string }) {
    const verificationCode = process.env.VERIFICATION_CODE;
    await getRepository(VerificationEntity).insert({ mobilePhone: body.receiver, verificationCode });

    const { id } = await getRepository(VerificationEntity).findOne();

    console.log('Check 3');

    return getRepository(VerificationEntity).findOne({ id: id as string });
  }
}

export default SecurityService;
