onDeactivation throws 'TypeError: Cannot convert undefined or null to object'

[saltylassi]

If container has both onActivation handler and onDeactivation, onDeactivation throws error.

Expected Behavior

working without error

Current Behavior

this error pops out

$ yarn build && node ./dist/main.js
$ tsc
blade instance Activation!

Possible Solution

Steps to Reproduce (for bugs)

1. follow these docs :

https://github.com/inversify/InversifyJS/blob/master/wiki/container_api.md#containeronactivationtserviceidentifier-interfacesserviceidentifiert-onactivation-interfacesbindingactivationt-void

https://github.com/inversify/InversifyJS/blob/master/wiki/container_api.md#ondeactivationtserviceidentifier-interfacesserviceidentifiert-ondeactivation-interfacesbindingdeactivationt-void

https://github.com/inversify/InversifyJS/blob/master/wiki/deactivation_handler.md#deactivation-handler

2. run this sample :

@injectable()
export interface IBlade {
  sharpness: number;
}

export class Blade implements IBlade {
  constructor(@optional() public sharpness: number = 5) {}
}

const container = new Container();
container.bind<IBlade>(IDENTIFIERS.Blade).to(Blade).inSingletonScope();
container.onActivation(IDENTIFIERS.Blade, () => {
  console.log('blade instance Activation!');
});
container.onDeactivation(IDENTIFIERS.Blade, (blade: IBlade): void | Promise<void> => {
  console.log('blade instance deactivation!');
});

container.get<IBlade>(IDENTIFIERS.Blade);
container.unbind(IDENTIFIERS.Blade);

3. error occurs

Stack trace

[oscar60310]

I've got the same error message but with a different scenario. I accidentally bound "undefined" on the container:

import 'reflect-metadata';
import { Container } from 'inversify';
const container = new Container();
container.bind('Test').toConstantValue(undefined);
console.log(container.get('Test')); // undefined
container.unbindAll(); // Error: Cannot convert undefined or null to object

This issue can be resolved by removing improper binding.

We're facing same error on container.unbindAll() call after inversify upgrade:

"inversify": "6.0.2",
"typescript": "4.9.5"
