-src/tests/fixtures/interfaces/InterfaceMergedIntoNode.invalid.ts:4:11 - error: Unexpected merged interface. If an interface is declared multiple times in a scope, TypeScript merges them. To avoid ambiguity Grats does not support using merged interfaces as GraphQL definitions. Consider using a unique name for your TypeScript interface and renaming it.

If you are trying to implement dependency injection, consider using the `context` argument passed to each resolver instead. If you have a strong use case for a concrete root value, please file an issue.
