Get an error "Cannot read properties of undefined (reading 'query')" when load the module by module federation

[zshlomyz]

I'm using @angular-architects/module-federation to split the code into micro frontends.
I'm using named client in my MFE to support multiple clients.
The module (module1) that use Apollo is configured like that:

  imports: [...,
HttpClientModule
    ApolloModule],
  providers:
  [
    {
      provide: APOLLO_NAMED_OPTIONS,
      useFactory: (httpLink: HttpLink) => {
        return {
          client1: {
          cache: new InMemoryCache(),
          link: httpLink.create({
            uri: myUrl,
          }),
        }};
      },
      deps: [HttpLink],
    }
  ]

I'm using the named client on the query like that:
query myQuery{ data @namedClient(name: "client1") .....
and use it like that:

this.apollo.watchQuery({
      query: <reference to query....>,
    }).valueChanges.subscribe(res=><handle the data..>)

When I run the MFE by itself, it bootstraped by the app.module of the MFE load module1 and the ApolloModule and it works.
When I load module1 using @angular-architects/module-federation, the app.module of the shell is import the ApolloModule but there is an error:

ERROR TypeError: Cannot read properties of undefined (reading 'query')
    at myQueryGQL.fetch (ngApollo.mjs:347:16)
    at MyComponent.ngOnInit (my-component.component.ts:86:43)

To Reproduce
Steps to reproduce the behavior:

Another try
I've also tried to solve it by replacing the myQueryGQL with apollo code like that -

export class MyService {
private apollo: ApolloBase;

    constructor(private apolloProvider: Apollo) {
        this.apollo = this.apolloProvider.use('client1');
    }
getData(...){
this.apollo.watchQuery({
                query: MyDocument,
                variables:{...}
            }).valueChanges.subscribe(res=><handle the data>);
}
}

When I used this syntax it works by making the call trough a component of the MFE but when I make the call at a service at the MFE I got the error:

ERROR TypeError: Cannot read properties of undefined (reading 'watchQuery')
    at MyService.getData (myService.service.ts:39:40)
    at MyComponentComponent.ngOnInit (my-component.component.ts:86:8)

Hi, I'm still facing the issue - no way to use the package at a micro frontend application. Can you help, please?

Hi! I am facing the same issue! It seems that the library have no idea about how to share or reuse the instance in the mfe remotes. Hope we could find a solution soon 😞
In the meantime we are looking for an alternative package or just do the post the old way.
