error : not able to download schema having union type

[WISKesarkar]

While working on POC for GQL federation to support multiple gql apis under one service. I found out nautius/gateway library fails to download schema with union types in it.

for testing Please refer this POC-example

Issue :

• serviceB gql schema has union named UnionTypeTest, service schema is downloaded using get-graphql-schema cli (schema is available in serviceB package and has union field with correct member types)
• When gatwayTest.go tries to fetch the schema from nautilus/gatway it fails to grab schema for union members and GQL Playground throws attached error.

@WISKesarkar Have you found any solution to this?

I am facing the same problem in case of Union.

@WISKesarkar Thank you for opening and for sharing a very easy-to-reproduce example. :clap: I've reproduced and it appears this was fixed by github.com/nautilus/graphql@v0.0.21.

I've bumped the gateway's dependency on graphql. I'll get that merged and cut a new release that includes the fix.

New release v0.3.14 includes the fix. Please shout if this did not address your issue!
