[SUPPORT] Cannot read property 'roles' of undefined

[vishnu-dev]

I have set up all the roles properly and have used decorators in my controller, but it throws an error. What am I doing wrong here, I followed the documentation.

Roles

appRoles
  .grant('superadmin')
  .createAny(['clients', 'users'])
  .readAny(['clients', 'users'])
  .updateAny(['clients', 'users'])
  .deleteAny(['clients', 'users'])

Controller

@UseGuards(JwtAuthGuard, ACGuard)
@UseRoles({
	resource:  'users',
	action:  'read',
	possession:  'any',
})
@Get()
allUsers(@UserRoles() userRoles: any) {
  console.log(userRoles);
  return this.userService.findAll();
}

req.user gives

{
  id: 'uuid',
  firstName: 'John',
  lastName: 'John',
  email: 'john@doe.com',
  createdAt: 2020-04-23T12:15:41.494Z,
  updatedAt: 2020-04-23T12:15:41.494Z,
  roles: [ 'superadmin' ]
}

The error

That happens because ACGuard has the asumption that you are saving the roles in the user header. Make sure to make it accesible in the user object by req.user.roles
