req.user if undefined in guards whileusing nest js + jwt + passport - node.js

Question

I've implemented passport + jwt in my simple nestjs app for authentication. it's working fine. Now I want to use role-based authentication for routes but in my role.guard.ts , req.user is undefined. Please help me solve this issue.
auth.guard.ts
import { Injectable } from '#nestjs/common';
import { AuthGuard } from '#nestjs/passport';
#Injectable()
export class JwtAuthGuard extends AuthGuard('jwt') {}
jwt.strategy.ts
import { Injectable } from '#nestjs/common';
import { ConfigService } from '#nestjs/config';
import { PassportStrategy } from '#nestjs/passport';
import { ExtractJwt, Strategy } from 'passport-jwt';
import { UserService } from 'src/user/user.service';
import { AuthService } from './auth.service';
#Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
constructor(
public authService: AuthService,
public configService: ConfigService,
public userService: UserService,
) {
super({
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
ignoreExpiration: false,
secretOrKey: configService.get('JWT_SECRET'),
// passReqToCallback: true,
// secretOrKey: authService.getConfig('JWT_SECRET'),
});
}
async validate(payload: any) {
const user = await this.userService.getOne(payload._id);
console.log('user', user);
return user;
// return { id: payload._id };
}
}
user.controller.ts
#Controller('users')
export class UserController {
constructor(private userService: UserService) {}
#Get('/')
#UseGuards(AuthGuard('jwt'))
#UseGuards(RolesGuard)
getAllUsers(): any {
return this.userService.getAll();
}
}
role.guard.ts
import { Injectable, CanActivate, ExecutionContext } from '#nestjs/common';
import * as jwt from '#nestjs/jwt';
import { promisify } from 'util';
#Injectable()
export class RolesGuard implements CanActivate {
canActivate(context: ExecutionContext): boolean | Promise<boolean> {
const req = context.switchToHttp().getRequest();
console.log('req.user', req.user);
return true;
}
}

Don't use two #UseGuards(), use a single one and order the guards in the order you want them to execute:
#UseGuards(AuthGuard('jwt'), RolesGuard)
