Nested pagination does not work with projection #4424
Description
Is there an existing issue for this?
- I have searched the existing issues
Describe the bug
I am using HotChocolate 12.2.0 with Entity Framework 5.0.10 and when trying to add nested pagination to a query with projection, an error is thrown. I expect no error to be thrown and the nested data to be retrieved by the query and also be able to be paged.
Have also tried adding ResolveWith to the Assets field and the same error is thrown.
Steps to reproduce
public record Account
{
public string Name { get; set; } = null!;
public ICollection<Asset> Assets { get; set; } = new List<Asset>();
}
public record Asset
{
public string Name { get; set; } = null!;
}
public class AccountType : ObjectType<Account>
{
protected override void Configure(IObjectTypeDescriptor<Account> descriptor)
{
descriptor
.Field(d => d.Name)
.Description("Name of the account.");
descriptor
.Field(d => d.Assets)
.UsePaging()
.UseProjection()
.UseFiltering()
.UseSorting();
}
}
public class AssetType : ObjectType<Asset>
{
protected override void Configure(IObjectTypeDescriptor<Asset> descriptor)
{
descriptor
.Field(d => d.Name)
.Description("Name of the asset.");
}
}
public class AccountResolver
{
public IEnumerable<Account> GetAccounts([Service] IRepositoryBase<Account> accountRepo)
{
return accountRepo.GetAll();
}
}
public class AssetResolver
{
public IEnumerable<Asset> GetAssets([Service] IRepositoryBase<Asset> assetRepo)
{
return assetRepo.GetAll();
}
}
public class Query : ObjectType
{
protected override void Configure(IObjectTypeDescriptor descriptor)
{
descriptor
.Field("accounts")
.ResolveWith<AccountResolver>(d => d.GetAccounts(default!))
.UsePaging()
.UseProjection()
.UseFiltering()
.UseSorting();
descriptor
.Field("assets")
.ResolveWith<AssetResolver>(d => d.GetAssets(default!))
.UsePaging()
.UseProjection()
.UseFiltering()
.UseSorting();
}
}The Repositories are simple wrappers over the Entity Framework DbSet for that type
