EF Core error

repo: https://github.com/mhamri/ef-int32-bug

applying oData queries on top of projected IQueryable throwing error. this was not the case for the older version.

Source/destination types

source:

public class Store
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public int OwnerId { get; set; }
        public Person Owner { get; set; }

        public ICollection<Book> Books { get; set; }
        public ICollection<BookStore> BookStore { get; set; }

    }

destination

public class StoreModel
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public PersonModel Owner { get; set; }

        public ICollection<BookModel> Books { get; set; }
        public IEnumerable<BookStoreModel> BookStore { get; set; }

    }

Mapping configuration

CreateMap<Person, PersonModel>();
CreateMap<Book, BookModel>();
CreateMap<Store, StoreModel>();
CreateMap<BookStore, BookStoreModel>();

Version: 10.1.1

Expected behavior

like the previous version return result!

Actual behavior

throwing error

System.InvalidOperationException: Rewriting child expression from type 'System.Int32' to type 'System.Nullable`1[System.Int32]' is not allowed, because it would change the meaning of the operation. If this is intentional, override 'VisitUnary' and change it to allow this rewrite.

I'm not sure why even there is a nullable value

Steps to reproduce

please check the repo

That looks like an EF Core issue. Check the execution plan. Run that as a LINQ statement, without AM. You should get the same result.
