In my application, I have a module called UserModule that exports the UserService. Here is an example of how it is done:
@Module({
imports: [
MongooseModule.forFeature([{ name: User.name, schema: UserSchema }]),
MongooseModule.forFeature([{ name: Profile.name, schema: ProfileSchema }]),
],
controllers: [UserController],
providers: [UserService],
exports: [UserService],
})
export class UserModule {}
RolesGuard Issue:
@Injectable()
export class RolesGuard implements CanActivate {
constructor(
private reflector: Reflector,
@Inject(UserService) private readonly userService: UserService,
) {}
// Rest of the code from canActivate function goes here
}
...However, when I try to inject the user service in RolesGuard, I encounter an error message for each module that uses the guard:
Error: Nest can't resolve dependencies of the RolesGuard (Reflector, ?). Please make sure that the argument UserService at index [1] is available in the CoachModule context.
Potential solutions:
- Is CoachModule a valid NestJS module?
- If UserService is a provider, is it part of the current CoachModule?
- If UserService is exported from a separate @Module, is that module imported within CoachModule?
@Module({
imports: [ /* the Module containing UserService */ ]
})
I am looking for a solution to this issue so that I don't have to manually import the user service into every module where RolesGuard is used.
