Introspection result missing interfaces

[martinformi]

I am using graphiql with spring-boot-graphql-starter, however I am getting an error even with the simple schema. Can you please verify what is wrong with the response from introspection? Thank you.

Error:

Hey 👋

This might be a bug in the spring-boot starter, the error is basically saying that the interfaces property is missing from the Deployment Object type. GraphiQL tries to do an introspection, it gets a set of object-types but the nullable interfaces array seems to be undefined, i.e. the key isn't present.
