Custom Provider: Object literal may only specify known properties, and 'provide' does not-CodePudding

I'm trying to replace my logger provider in a unit test file with a stubbed provider so that I don't get logs during unit tests from the tested module. I'm getting the following error:

error TS2322: Type '{ provide: string; useValue: {}; }' is not assignable to type 'Type<any> | DynamicModule | Promise<DynamicModule> | ForwardReference<any>'.
      Object literal may only specify known properties, and 'provide' does not exist in type 'Type<any> | DynamicModule | Promise<DynamicModule> | ForwardReference<any>'.  

    21           provide: WINSTON_MODULE_PROVIDER,

My Code:


  beforeEach(async () => {
    const moduleRef = await Test.createTestingModule({
      providers: [MyService],
      imports: [
        {
          provide: WINSTON_MODULE_PROVIDER, // Error on this line
          useValue: {},
        },
      ],
    }).compile();

    MyService = moduleRef.get<MyService>(MyService);
  });

And here's the constructor of the module i'm testing

constructor(
    @Inject(WINSTON_MODULE_PROVIDER) private readonly logger: Logger,
  ) {}

Custom providers go in the providers array, not the imports. Providers never go in the imports array.
