Issue with Authorizer not being found by Nest as a dependency

[smolinari]

Hi,

would anyone have an idea why this might be happening or what I'm doing wrong to get it?

Error: Nest can't resolve dependencies of the UserDTOAuthorizerInterceptor (?). Please make sure that the argument UserDTOAuthorizer at index [0] is available in the UserModule context.

Potential solutions:
- If UserDTOAuthorizer is a provider, is it part of the current UserModule?
- If UserDTOAuthorizer is exported from a separate @Module, is that module imported within UserModule?
  @Module({
    imports: [ /* the Module containing UserDTOAuthorizer */ ]
  })

@JohnMcInall - Hey John. Sorry to ping you out of the blue, but I'm sorta stuck. 😁

Do you have any quick ideas for this problem? Are you still working with Nestjs-Query?

@smolinari Can you share the module importing the authorizer and the one exporting it?

[llanicm]

@smolinari Hey, this looks more like the NestJS DI container not having any knowledge of the Authorizer you are asking for. As @doug-martin said could you provide the module that imports and exports the authorizer?

[smolinari]

@doug-martin @JohnMcInall - That's just it. The user module doesn't have an Authorizer.

import { Module } from '@nestjs/common'
import { NestjsQueryTypegooseModule } from '@nestjs-query/query-typegoose'
import { NestjsQueryGraphQLModule } from '@nestjs-query/query-graphql'
import { UserEntity } from './user.entity'
import { UserAssembler, UserService } from './user.service'
import { UserResolver } from './user.resolver'

@Module({
  imports: [
    NestjsQueryGraphQLModule.forFeature({
      imports: [NestjsQueryTypegooseModule.forFeature([UserEntity])],
      services: [ UserService ],
      assemblers: [ UserAssembler ],
      resolvers: []
    })
  ],
  providers: [ UserService, UserResolver],
  exports: [UserService]
})
export class UserModule {}

Andddd... I don't believe it. Just the fact you said show the module, I went back to the docs and said, what the heck could I be missing? And then I read this:

WARNING
All of the subsequent examples omit the module definition for custom resolvers but you should still register your DTOs to ensure all the providers are set up properly.

So, I did this:

import { Module } from '@nestjs/common'
import { NestjsQueryTypegooseModule } from '@nestjs-query/query-typegoose'
import { NestjsQueryGraphQLModule } from '@nestjs-query/query-graphql'
import { UserEntity } from './user.entity'
import { UserAssembler, UserService } from './user.service'
import { UserResolver } from './user.resolver'
import { UserDTO, UserInputDTO, UserUpdateDTO } from './dtos'

@Module({
  imports: [
    NestjsQueryGraphQLModule.forFeature({
      imports: [NestjsQueryTypegooseModule.forFeature([UserEntity])],
      services: [ UserService ],
      assemblers: [ UserAssembler ],
      resolvers: [],
      dtos: [{
        DTOClass: UserDTO,
        CreateDTOClass: UserInputDTO,
        UpdateDTOClass: UserUpdateDTO
      }]
    })
  ],
  providers: [ UserService, UserResolver],
  exports: [UserService]
})
export class UserModule {}

And low and behold, and holy crap.... it is compiling. 😮

Thanks guys and sorry for wasting any time. 😊

It seems, if you don't add the DTOs to the module definition, nestjs-query isn't able to build the internal default authorizer and you get this error.

@doug-martin - I believe there is a setting you can turn on or change the type of discussions, so that a reply can be flagged as the answer. I added the comment above looking for that feature to be available, but it seems it isn't.
