NestJs - Unable to get user auth response on Bearer Token

I'm using NestJs as framework and jwt for auth. I tried to login to the endpoint using user credentials, then I receive a jwt token as a response. After that, I use that token (bearer token) to get access to all the users info(code below) but I'm getting the following error:

Error
[Nest] 17189   - 03/15/2021, 12:52:59 PM   [ExceptionsHandler] this.validate is not a function +47159ms

    at Object.module.exports [as verify] (/Users/axels18m/Desktop/Work/Testing/nest-twitter-project/node_modules/jsonwebtoken/verify.js:94:10)

Here is the endpoint where the error is raised (user.controller.ts)

@Controller('user')
export class UserController 
{
    constructor(
        private userService: UserService
    ) {}

    @hasRoles('admin')
    @UseGuards(JwtAuthGuard, RolesGuard)
    @Get()
    getAll(): Observable<User[]>
    { 
        return this.userService.getAll(); 
    }
}

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy)
{
    constructor(private configService: ConfigService)
    {
        super({
            jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
            ignoreExpiration: false,
            secretOrKey: configService.get('JWT_SECRET')
        });
    }

    async validator(payload: any)
    {
        return { 'user': payload.user , 'username': payload.username };
    }
}

Steps for getAll users:

@Post('login')
  login(@Body() user: User): Observable<Object>
  {
    return this.userService.login(user).pipe(
      map((jwt: string) => { return { access_token: jwt} })
    )
  }

In your JwtStrategy you have the async method valdiator not validate. This method needs to be validate in order for @nestjs/passport to send on the method properly to passport
