Could not find possible implementing types for VolumeInterface in schema

[LeeCampbellr]

I'm having an issue with the plugin running 1.2.1 - logged into my Craft install today and the CraftQL query plugin has this error:

{ "error": "Could not find possible implementing types for VolumeInterface in schema. Check that schema.types is defined and is an array of all possible types in the schema." }

Opened the Craft Debug panel and this error is in there:

Category: GraphQL\Error\InvariantViolation.

UPDATE:
I wonder if these depreciation warnings have anything to do with this?
