Current behavior

I get:

[Nest] 4578   - 10/10/2018, 4:43:26 PM   [ExceptionHandler] Nest can't resolve dependencies of the HttpService (?). Please make sure that the argument at index [0] is available in thecurrent context. +24ms

Expected behavior

The app should run just fine and the HttpService dependency can be injected in the AppModule.

Minimal reproduction of the problem with instructions

Install cli and perform the following steps:

1. run nest new app
2. edit app.module.ts (import HttpService from HttpModule), code diff

import { Module, HttpService, HttpModule } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';

@Module({
  imports: [HttpModule],
  controllers: [AppController],
  providers: [AppService, HttpService],
})
export class AppModule {}

1. run npm run start
   

   What is the motivation / use case for changing the behavior?

I would like to make some http requests in the nest app (download some files and then process them)

Environment

Nest version: 5.1.0


For Tooling issues:
- Node version: v10.9.0

hey fixed this yet?
if not, you don't need to set HttpService as a provider, only the HttpModule as a import. the HttpService is injected in the provider you're going to use.
image from the docs.

@barretojs thanks. I updated from nestjs major version 4, and for some reason, I had the HttpService listed in the providers. Nest-js version 4 won't complain about this.
Thanks again, closing the issue

Here is the BitcoinService file:

@Injectable()
export class BitcoinService {

    constructor(private http: HttpService) {

}

Here is the AppModule:

Hi werewolf,
My issue was due to the missing reference.

I guess you would need to include 'BitcoinService' ref in your module. I had a separate ts file. so I just included it with the @Module ({components: [HERE_IT_GOES],}). Hope it helps.

@werewolfe, i was facing the same issues but this worked for me.
change your imports section to look like :

imports: [HttpModule.register({
      timeout: 5000,
      maxRedirects: 5,
    }),],
