Is it possible to add a field to an interface in an existing graphql schema?


I’ve tried to add a field to an existing interface, all types that implement this interface have the field, the update of the schema is succesful, and I can see the field in the interface and query it, but it returns only null values, even though there is data for this field. Is there something else I have to do?

I’m using dgraph version 21.03.2
