Describe the bug

Error: src/app/API.service.ts:1388:12 - error TS2352: Conversion of type 'Observable<GraphQLResult<any>> | Promise<GraphQLResult<any>>' to type 'Observable<SubscriptionResponse<Pick<__SubscriptionContainer, "onUpdateComment">>>' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
  Type 'Promise<GraphQLResult<any>>' is missing the following properties from type 'Observable<SubscriptionResponse<Pick<__SubscriptionContainer, "onUpdateComment">>>': subscribe, forEach, map, filter, and 4 more.

1388     return API.graphql(
                ~~~~~~~~~~~~
1389       graphqlOperation(statement, gqlAPIServiceArguments)
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 ...
1391       SubscriptionResponse<Pick<__SubscriptionContainer, "onUpdateComment">>
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1392     >;

These repeat mostly for all GraphQLResults at bottom of file. Fails to compile. I attempted to roll back to older versions but have not made it go away.

Expected behavior

It compiles w/o error.

Reproduction steps

1. Installed Node 16+, Angular 14+, Amplify CLI
2. Created ng new 14Test project
3. amplify init
4. amplify add api
5. Used graphql, boilerplate example
6. performed codegen
7. API.service.ts created
8. add to project
9. ng s -o (serve and open) - fails

I've attempted to roll back to older versions of @aws-amplify/api-graphql but that did not have any effect.

Code Snippet

  OnCreateBlogListener(
    filter?: ModelSubscriptionBlogFilterInput
  ): Observable<
    SubscriptionResponse<Pick<__SubscriptionContainer, "onCreateBlog">>
  > {
    const statement = `subscription OnCreateBlog($filter: ModelSubscriptionBlogFilterInput) {
        onCreateBlog(filter: $filter) {
          __typename
          id
          name
          posts {
            __typename
            nextToken
          }
          createdAt
          updatedAt
        }
      }`;
    const gqlAPIServiceArguments: any = {};
    if (filter) {
      gqlAPIServiceArguments.filter = filter;
    }
    return API.graphql(
      graphqlOperation(statement, gqlAPIServiceArguments)
    ) as Observable<
      SubscriptionResponse<Pick<__SubscriptionContainer, "onCreateBlog">>
    >;
  }
