[Question] Container not initialised when used in bootstrap

[aminmc]

Hello,

Apologies if this isn't the right place to ask this but I'm stuck on the following scenario:

I have a class that initialises a container and do the following:

 this.container.load(buildProviderModule());

In my bootstrap class I try to get a service class from the container:

const applicationContext: ApplicationContext = new ApplicationContext();

const container = applicationContext.iocContainer();

const server = new InversifyExpressServer(container);

server.setConfig((app) => {
    const keycloakService: KeycloakService = container.get(TYPE.KeycloakService);
    app.use(keycloakService.middleware());
    app.use(bodyParser.urlencoded({
        extended: true,
    }));
    app.use(bodyParser.json());
});

When I start my bootstrap class I get the following exception:

Error: No matching bindings found for serviceIdentifier: Symbol(KeycloakService)
    at _validateActiveBindingCount (/Users/aminmc/Development/typescript-example/node_modules/inversify/lib/planning/planner.js:62:23)

If I explicitly add the class to the container then it works.

  this.container.bind<KeycloakService>(TYPE.KeycloakService).to(KeycloakService);

My service class looks

@provide(TYPE.KeycloakService)
export class KeycloakService {
..
}

It looks as though the KeycloakService hasn't been registered by the time I call the container to get the class. The Keycloak Service resides in a different package from the ApplicationContext class where I initialise the container.

Is there a way force the container to be initialised before I call the container to get the class? Or am I missing a set up method?

Any help would be appreciated.
