Graphql-tools: buildSchemaFromTypeDefinitions crashes on type implementing multiple interfaces

Created on 9 Feb 2018 · 5Comments · Source: ardatan/graphql-tools

I just upgraded my apollo / graphql-tools packages to latest and ran into this running my test suite.

When parsing a schema containing this line, the tests error out with GraphQLError: Syntax Error: Unexpected Name GeoInCounty

type ZipCode implements Geo, GeoInCounty, GeoInState {
  fullyQualifiedName: String!

So it seems like it can't handle this multi implements syntax.

Stack trace:
