nestjs cannot find HEADER parameter

Question

I was passing JWT-token from the postman on my local machine, and I can decode it into some data inside. But for some reason when I push it onto the docker container and throw a request to my API, it can't see my header properly.

Here is my code, written on nestjs.

user.controller.ts

import { UserService } from '../services'
import { Body, Controller, Get, Headers, Param, Patch } from '@nestjs/common'
import { UserDto } from '../types/dtos'

@Controller()
export class UserController {
  constructor (
    private readonly service: UserService
  ) {}

  @Get('/api/get-user-data')
  async getUser (@Headers('access_token') token: string) {
    return await this.service.getUserByToken(token)
  }

user.service.ts

import jwtDecode from 'jwt-decode'
import { TokenDto } from '../types/dtos/token.dto'

@Injectable()
export class UserService {
  userProfileMapper = new UserProfileMapper()
  constructor (
    @Inject(CREATOR) private readonly repository: BaseRepository<Creator>,
  ) {}

 async getUserByToken (token: string) {
    try {
      const object: TokenDto = await jwtDecode(token)
      const user = await this.repository.get({email: object.email})
      return this.userProfileMapper.toDTO(user)
    } catch (e) {
      console.log(e)
    }
  }
}

Can it be a problem in the docker container or something else?
