Describe the bug

graphql-mesh/compose cannot consume graph generated by itself

To Reproduce Steps to reproduce the behavior:

run:

$ npm i @graphql-mesh/compose-cli
$ npm i @graphql-hive/gateway

create 2 files:

mesh.orig.ts

import {
  defineConfig,
  loadGraphQLHTTPSubgraph
} from '@graphql-mesh/compose-cli'

export const composeConfig = defineConfig({
  subgraphs: [
    /**/{
      sourceHandler: loadGraphQLHTTPSubgraph('MortyB', {
        endpoint: 'https://rickandmortyapi.com/graphql'

      }),
    },
  ]
})

mesh.hive.ts

import {
  defineConfig,
  loadGraphQLHTTPSubgraph
} from '@graphql-mesh/compose-cli'

export const composeConfig = defineConfig({
  subgraphs: [
    /**/{
      sourceHandler: loadGraphQLHTTPSubgraph('MortyB', {
        endpoint: 'http://localhost:5001/graphql'

      }),
    },
  ]
})

run following

$ npx mesh-compose -c mesh.orig.ts -o supergraph_orig.graphql
$ npx hive-gateway -p 5001 supergraph_orig

in other terminal run

$ npx mesh-compose -c mesh.hive.ts -o supergraph_hive.graphql

error message:

ERROR [Mesh Compose, subgraph=MortyB]  Schema must contain uniquely named types but contains multiple types named "TransportOptions".
ERROR [Mesh Compose, subgraph=MortyB]  Failed to load subgraph

Expected behavior

The graph can be composed and used

Sorry I didn't understand the setup you have. Could you please create a reproduction on CodeSandbox? Thanks!

there are two commands, "start" is the started server, and "start2" tries to extract graphql from it and compose it ...

my final goal is to be able to chain supergraphs into supersupergraph, possibly even to supersupersupergraph :-)

[ardatan]

Unfortunatrly that kind of chaining is not possible today
