How to Authenticate logged in user in NestJs with Swagger - node.js

Question

I just started using nestjs for a project. I have successfully logged in users and token returned. Now using the token to authorize users is the problem. Trying to get all users has been returning "unauthorized access"
I am also thinking I didn't put the token correctly or so. In the swagger authorization UI, I supplied
Bearer someTokenGoesHere into the input box
Image below
This is my code
main.ts
Swagger configuration in main.ts
const options = new DocumentBuilder().addBearerAuth()
.setTitle('My app')
.setDescription('My app API description')
.setVersion('1.0')
.addTag('Tags')
.build();
const document = SwaggerModule.createDocument(app, options);
SwaggerModule.setup('', app, document);
User controller
import { Controller, Post, Body, Get, Param, UseGuards } from '#nestjs/common';
import { UserService } from './user.service';
import { CreateUserDto } from './create-user.dto';
import { LoginUserDto } from './login-user.dto';
import { AuthService } from 'src/auth/auth.service';
import { AuthGuard } from '#nestjs/passport';
import { AdminGuard } from 'src/guards/admin.guard';
import { ApiBearerAuth, ApiBasicAuth } from '#nestjs/swagger';
#Controller('user')
export class UserController {
constructor(private userService: UserService,
private authService: AuthService) { }
#Post('login')
async login(#Body() loginDTO: LoginUserDto) {
const user = await this.userService.login(loginDTO);
const newob = {
id: user._id
}
const payload = {
userId: user._id,
email: user.Email,
}
const token = await this.authService.signPayLoad(payload);
return { newob, token };
}
#Post('register')
async register(#Body() createDTO: CreateUserDto) {
const user = await this.userService.register(createDTO);
const newob = {
id: user._id
}
const payload = {
firstname: user.FirstName,
lastname: user.LastName
};
const token = await this.authService.signPayLoad(payload);
return newob;
}
#Get('all')
#ApiBearerAuth()
#UseGuards(AuthGuard('jwt'))
async getAllUsers() {
return await this.userService.getAllUsers();
}
#Post('confirm/:token')
async confirmEmail(#Param() token: string) {
const user = await this.userService.ConfirmEmail(token);
return user;
}
}
Can someone please help me out
Thanks

I was able to fix it, I appreciate your suggestions. I was extracting email that wasn't present in the payload. so I decided to log it and discovered it was null. Then I logout payload, I discovered I was passing User Id into the payload. So I change to id.
The result is
async findByPayLoad(payload: any) {
const { userId } = payload;
return await this.userModel.findById(userId)
}
