Upgrading to Build 700 caused error "Nullable object must have a value"

[LinusK]

I just upgraded to build 700 on my dev machine and got this error when the studio is accessing the database.

{

• Url: "/indexes/Raven/DocumentsByEntityName?query=Tag%253ATags&start=0&pageSize=0&aggregation=None",
• Error: "System.InvalidOperationException: Nullable object must have a value. at System.Nullable`1.get_Value() at Raven.Storage.Esent.StorageActions.DocumentStorageActions.IndexLastUpdatedAt(String name) in c:\Builds\RavenDB-Stable\Raven.Storage.Esent\StorageActions\Staleness.cs:line 132 at Raven.Database.DocumentDatabase.<>c__DisplayClass7f.<Query>b__77(IStorageActionsAccessor actions) in c:\Builds\RavenDB-Stable\Raven.Database\DocumentDatabase.cs:line 740 at Raven.Storage.Esent.TransactionalStorage.ExecuteBatch(Action`1 action) in c:\Builds\RavenDB-Stable\Raven.Storage.Esent\TransactionalStorage.cs:line 378 at Raven.Storage.Esent.TransactionalStorage.Batch(Action`1 action) in c:\Builds\RavenDB-Stable\Raven.Storage.Esent\TransactionalStorage.cs:line 339 at Raven.Database.DocumentDatabase.Query(String index, IndexQuery query) in c:\Builds\RavenDB-Stable\Raven.Database\DocumentDatabase.cs:line 730 at Raven.Database.Server.Responders.Index.PerformQueryAgainstExistingIndex(IHttpContext context, String index, IndexQuery indexQuery, Guid& indexEtag) in c:\Builds\RavenDB-Stable\Raven.Database\Server\Responders\Index.cs:line 174 at Raven.Database.Server.Responders.Index.ExecuteQuery(IHttpContext context, String index, Guid& indexEtag) in c:\Builds\RavenDB-Stable\Raven.Database\Server\Responders\Index.cs:line 160 at Raven.Database.Server.Responders.Index.GetIndexQueryRessult(IHttpContext context, String index) in c:\Builds\RavenDB-Stable\Raven.Database\Server\Responders\Index.cs:line 116 at Raven.Database.Server.Responders.Index.OnGet(IHttpContext context, String index) in c:\Builds\RavenDB-Stable\Raven.Database\Server\Responders\Index.cs:line 88 at Raven.Database.Server.Responders.Index.Respond(IHttpContext context) in c:\Builds\RavenDB-Stable\Raven.Database\Server\Responders\Index.cs:line 43 at Raven.Database.Server.HttpServer.DispatchRequest(IHttpContext ctx) in c:\Builds\RavenDB-Stable\Raven.Database\Server\HttpServer.cs:line 534 at Raven.Database.Server.HttpServer.HandleActualRequest(IHttpContext ctx) in c:\Builds\RavenDB-Stable\Raven.Database\Server\HttpServer.cs:line 309"

}

My Tag class looks like this:

    public class Tag

    {

        public string Id { get; set; }

        public string Name { get; set; }

        public string Description { get; set; }

        public override string ToString()

        {

            return this.GetPublicPropertiesAsString();

        }

    }

Is it a bug or did I do something wrong?

[Fitzchak Yitzchaki]

Can you write a failing test?

This is a passing one:

public class LinusK : RavenTest
{
	

public class Tag
	{
		public string Id { get; set; }
		public string Name { get; set; }
		public string Description { get; set

; }
	}
 
	[Fact]
	public void CanQuery()
	{
		using (var store = NewDocumentStore())
		using (var session = store.OpenSession())
		{
			session.Store(new Tag {Name = "tag"});
			session.SaveChanges();
 
			var tags = session.Query<Tag>()
				.Customize(x => x.WaitForNonStaleResultsAsOfNow())
				.ToList();
 
			Assert.Equal(1, tags.Count);
		}	
	}
}

And having the same problem with unstable build 709.

I actually don't see the how the test will help. Because the error occurred directly after the upgrade when the Studio accessed the server.

When I run your test on an in-memory store it succeeds. When I run it against regular store I get the same error as stated before:

System.InvalidOperationException: Nullable object must have a value.

[Oren Eini (Ayende Rahien)]

Is this against a NEW store, or against an existing store that was upgraded from an older build?

[LinusK]

It's from an upgraded store.

[Oren Eini (Ayende Rahien)]

Hm...

Okay, I think that I fixed this issue, please test this again with the next build.

[Linus Kvarnhammar]

Ok, when can I expect it?

[Oren Eini (Ayende Rahien)]

A few hours, at most.

[Linus Kvarnhammar]

That seemed to fix it. Thanks!

But the studio is broken. Crashes hard at load time.

/Linus

[Oren Eini (Ayende Rahien)]

Yeah, unstable is as as unstale as the name suggest.

We try to do better though, and we will have a better build soo

[Linus Kvarnhammar]

Maybe you could introduce voting on builds - like R# EAP. Could be a good idea both for Stable and Unstable builds. 

And when I'm at it would also like to suggest better release notes - so that I know if I should upgrade or not.

[Oren Eini (Ayende Rahien)]

Working on both things, yes

[Dave Baird]

When is the next stable build coming out that has this fix included?  We need to upgrade Raven in a production environment to fix a separate issue and when we went to 701 this cropped up.

Thanks,

Dave B

Hopefully tomorrow
