Strawberry Shake: Runtime ArgumentNullException caused by possible code generation bug when mapping response into "Data" object

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I'm in the situation where shake is not able parse the response and throws.

Steps to reproduce

I have created a repro repo where you can find my query that causes the problem.

I have a Listing. Listing is implemented by ListingSimple and Projekt. ListingSimple is implemented by Offer and Auction. Project has a field listings that is selection wrapper around [ListingSimple!]!.

I also have a query listing(..): [Listing]! where I would like to query all project listings. But it seems that Shake threats all Listings the same - I mean that if I query for non nullable field in "child project listings" it also nullchecks for that field in the "parent project listing" even though I did not query for that particular field (it is not present in the response) so an ArgumentNullException is thrown.

Relevant log output

System.ArgumentNullException: Value cannot be null.

Additional Context?

Note: I'm 100% sure that there is no null value in non-nullable field.
