Adding a versioned GraphQL schema as a Hasura remote schema.

Description

I am currently testing on a project in Hasura and thought it would be interesting to add a SilverStripe GraphQL scheme. Unfortunately, I get an error when I do this:

The type of Object field 'SiteTree'."versions" (ModelPageVersionConnection) is not the same type/sub type of Interface field 'SiteTreeInterface'."versions" (SiteTreeVersionConnection)

I did manage to add the schema when versioning is disabled. Does anyone have any idea what it could be due to. Unfortunately, I am not getting any wiser from the generated schema....

How to reproduce

• Run a Hasura instance on your pc via Docker.
• Run a SilverStripe instance on your pc.
• Make sure that the GraphQL endpoint is reachable.
• Make sure versioning is enabled/installed for models in the schema.
• Add the SilverStripe GraphQL endpoint as a remote schema in hasura.

Possible Solution

Let ModelPageVersionConnection implement the SiteTreeVersionConnection interface

From the error you provided, it doesn't look like the issue you are having is specific to Hasura.

Can you provide the definition used to create your GraphQL schema and provide a query that replicate the issue.
