Error on generating code for non nullable ICollection<Guid>

[mwilde]

Describe the bug

If you have a DTO (maybe record) with a non nullable property ICollection<Guid> MyValues than the generated schema.graphql looks great: input MyDtoInput { myValues: [UUID!]! }

But the code generator for StrawberryShake throws an error on generating process: Non-Nullable-Feld "_value_myValues" muss beim Beenden des Konstruktors einen Wert ungleich NULL enthalten. Erwägen Sie eine Deklaration von "Feld" als Nullable.

To get the process working the only possibility is to mark ICollection<Guid>? MyValues as nullable.

Steps to reproduce

1. Create DTO public record MyDto( ICollection<Guid> MyValues);
2. Create DTO public record MyInput( MyDto MyValue)
3. Update schema with dotnet graphql update
4. Create mutation mutation SendMyInput( $dto:MyInput!){ sendMyInput( input: $dto ) }
5. The code generator throws the error

Relevant log output

Non-Nullable-Feld "_value_myValues" muss beim Beenden des Konstruktors einen Wert ungleich NULL enthalten. Erwägen Sie eine Deklaration von "Feld" als Nullable.

@mwilde can you share query and schema?

[mwilde]

@PascalSenn here is my schema and the mutation:

schema { mutation: Mutation }

type Mutation { setMyValue(input: SetMyValueInput!): SetMyValuePayload! }

type SetMyValuePayload { errors: [UserError!]! }

scalar UUID

type UserError { message: String! }

input SetMyValueInput { myValue: MyDtoInput! }

input MyDtoInput { myIds: [UUID!]! }

mutation SetMyValue( $dto:SetMyValueInput!){ setMyValue( input: $dto ){ errors { message } } }

@PascalSenn the same error occurs if you have a collection of type Enum.
