[oskargotte]

Bump sangria-federation to latest version which supports the @interfaceObject directive. Add the Inventory entity object type with Key and InterfaceObject directives to the schema in order to pass the compatibility test for @interfaceObject.

@oskargotte is this still a draft?

Looks like @composeDirective (https://github.com/sangria-graphql/sangria-federated/issues/221) is also supported. Do you mind updating the test to also cover that scenario?

Well it’s pretty much finilized but I wanted to give @yanns a chance to provide feedback before merging it.

Yes the composeDirective is supported in sangria-federated but I'll have to read up on the requirements to get the tests to pass. I can target that one in another PR.
