How can setup Graphql Federation with apolloGateway in nestjs

Question

Main App imports

imports: [
    GraphQLModule.forRoot<ApolloGatewayDriverConfig>({
      driver: ApolloGatewayDriver,
      gateway: {
        supergraphSdl: new IntrospectAndCompose({
          subgraphs: [
            { name: 'users', url: 'http://localhost:3331/graphql' },
            { name: 'homes', url: 'http://localhost:3332/graphql' },
          ],
        }),
      },
    }),
  ],`

2 sub app config

  imports: [
    GraphQLModule.forRoot<ApolloFederationDriverConfig>({
    driver: ApolloFederationDriver,
    autoSchemaFile: {
      federation: 2,
    },
  }),
]

It gives this error

couldn't load service definitions for "homes" at http://localhost:3332/graphql: 400: Bad Request at somelse\estate\node_modules@apollo\gateway\src\supergraphManagers\IntrospectAndCompose\loadServicesFromRemoteEndpoint.ts:77:15
at processTicksAndRejections (node:internal/process/task_queues:95:5) at async Promise.all (index 1)

I need help to solve this or any better way to do it.
