ah yes: here is my error and here is the output from npx -y @nestjs/cli good luck
could you at least tell us what you where doing? or even better show the code that caused it?

[cobalt berry]

@onyx thicket sorry, I thought this was enough as the error pretty much says what I was trying to do. I can't access the createDecorator property of Reflector. I was following this doc,
https://docs.nestjs.com/guards#setting-roles-per-handler

Reflector.createDecorator was introduced in v10 which I'm using but still can't access the createDecorator property.

error is kinda vuage for all i could know is some kind of custom decorator

ah i see what you're trying to do
just a guard decorator

[onyx thicket]

can you show how your guard looks like?
and your end point (in your controller) where the guard is being used?

[cobalt berry]

This is my guard

@Injectable()
export class AuthGuard implements CanActivate {

  constructor(private reflector: Reflector) { }


  canActivate(
    context: ExecutionContext,
  ): boolean | Promise<boolean> | Observable<boolean> {

    const userTypes = this.reflector.get<UserType[]>('userTypes', context.getHandler())

    if (!userTypes || userTypes.length == 0) {
      return true
    }

    const request = context.switchToHttp().getRequest()

    const user: UserSafe = request.user

    if (!user) {
      return false
    }

    return userTypes.includes(user.type)
  }

}

I'm using it in a controller like this,

@Controller('flight')
@UseGuards(AuthGuard)
export class FlightController {

    constructor(private readonly context: ContextService) { }

    @Get()
    // @Auth('SUPERADMIN')   <---- Can't use this since can't create the decorator at all
    async test(): Promise<string> {
        return "Hello World!";
    }
}

The code mentioned on the doc is not working it self, so can't use this anywhere. createDecorator is highlighted red.

import { Reflector } from '@nestjs/core';

export const Roles = Reflector.createDecorator<string[]>();
