Inversifyjs: Can't instantiate a class manually inside another class (ERROR_MSGS.NULL_ARGUMENT)

[m3l7]

I'm not sure if I'm following the right approach here.

Basically I have to classes (ClassA, classB) and I'm trying to instantiate classA inside classB.

  // inversify.js
  import {ClassA} from './classA';
  import {ClassB} from './classB';
  inversifyContainer.bind<ClassA>(ClassA).toSelf();
  inversifyContainer.bind<ClassB>(ClassB).toSelf();

  // classB
  method() { inversifyContainer.get<ClassA>(ClassA);

I got this error

  /mnt/dati/Sorgenti/backend/backend-backend/node_modules/inversify/lib/container/lookup.js:13
              throw new Error(ERROR_MSGS.NULL_ARGUMENT);
              ^

If I define ClassB inside inversify.ts rather than in a separate file, everything is working correctly.

using node 8.9.4, typescript 2.3.4 (tried with 2.7 too), last version of inversify

I managed to solve the issue. Basically in my entry point source (the script actually being run) I was importing some modules before loading the inversify.ts module and at the same time I was importing the "reflect-metadata" package in every module.

Removing the multiple metadata import and keeping the inversify.ts import at the beginning solves.
