Error importing examples schema

I was trying to import the schema from dgraph/graphql/resolve/schema.graphql and it returned me an error:

{"errors":[{"message":"resolving updateGQLSchema failed because input:494: interface is not supported as an argument for id directive.\n (Locations: [{Line: 3, Column: 4}])","extensions":{"code":"Error"}}]}

What version are you using? And are you following some tutorial? which one?

I was trying those examples. I updated dgraph to the latest a few days ago.

Looks like you should be using master(?). Or you are missing something. These are test files, they have a context to run. You can check the latest PR tests(not sure if they are public) to see that there are no errors.
