ArgumentNullException while rendering package page

[Konstantin]

I have a feed with connector to official nuget feed. (
When accessing http://nuget.it.unistreambank.ru/feeds/DEV.Libs/RavenDB.Client I get the following error (for other packages from official nuget feed everything looks fine):

That error indicates that the NuGet package is missing an ID element in the .nuspec file. Can you post the .nuspec file here to verify?

[Konstantin]

As I wrote in first message it comes from official nuget feed via connector. You may get the package here https://www.nuget.org/packages/RavenDB.Client/2.5.2700
Native nuget tools cmd line and VS plugin have no problem with it.

[Tod]

Thank you for the report - we've been able to repro this behavior in our testing environment. Once we determine the problem, we will publish a new maintenance release to address the issue.

[Konstantin]

I've upgraded to 2.2.0
Now the package (https://www.nuget.org/packages/RavenDB.Client/2.5.2700) page is ok, but when I try to install this package i get an error. I've found workaround:
manually "pull to proget" the package and all it's dependencies one by one , I can install it from proget.

If I try to pull the package with "dopwnload dependencies", I get the following exception:

What error are you getting when you try to install the package?

I'm able to reproduce the "download dependencies" issue, but I haven't had any problems downloading or installing that package.

[Konstantin]

Sorry, I described the situation wrong (got error message on build server and did not notice that it is not compilation time error but error from my app started by the build ).

I use Nuget.Core to install plugins and their dependencies in my application and it failes to install RavenDb.Client package.

Exception I get:

System.InvalidOperationException : Unable to find version '2.5.2700' of package 'RavenDb.Client'.
at NuGet.PackageRepositoryHelper.ResolvePackage(IPackageRepository sourceRepository, IPackageRepository localRepository, IPackageConstraintProvider constraintProvider, String packageId, SemanticVersion version, Boolean allowPrereleaseVersions)
at NuGet.PackageManager.InstallPackage(String packageId, SemanticVersion version, Boolean ignoreDependencies, Boolean allowPrereleaseVersions)
at NuGet.PackageManager.InstallPackage(String packageId, SemanticVersion version)

Here is a test reproducing the issue:

[TestFixture]
public class NugetInvestigation
{
[Test]
[Ignore]
public void ProgetResolutionErrorDemoTest()
{
var tmpRepo = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString());
Directory.CreateDirectory(tmpRepo);
try
{
Console.WriteLine(tmpRepo);
var manager = new PackageManager(PackageRepositoryFactory.Default.CreateRepository("http://nuget.it.unistreambank.ru/feeds/DEV.Libs"), tmpRepo) { Logger = new NugetConsoleLogger() };
manager.InstallPackage("RavenDb.Client",new SemanticVersion("2.5.2700"));

        }
        finally
        {
            Directory.Delete(tmpRepo,true);
        }
      
    }

    public class NugetConsoleLogger : NuGet.ILogger
    {
        public FileConflictResolution ResolveFileConflict(string message)
        {
            return FileConflictResolution.Ignore;
        }

        public void Log(MessageLevel level, string message, params object[] args)
        {
            Console.WriteLine("[" + level + "] " + message, args);
        }
    }

}

[Konstantin]

Sorry the test above is wrong. Issue occures when nuget resolves package with dependency on 'RavenDB.Client (= 2.5.2700)' while it is not pulled to proget.

Here is correct test (update progetRepo URL to your local proget, please ). It creates package depnedent on RavenDB.Client and tryes to install it. When RavenDB.Client is pulled to proget it works fine , when RavenDB.Client is available only via connector it crashes with

System.InvalidOperationException : Unable to resolve dependency 'RavenDB.Client (= 2.5.2700)'.

Hmm, thanks for the repro code.

Can you try running a Fiddler trace to see what calls to the ProGet server this is trying to use?

[Konstantin]

fiddler export:
https://dl.dropboxusercontent.com/u/1055156/proget.saz

there are only three requests and looks like you need this one:
GET http://nuget.it.unistreambank.ru/nuget/DEV.Libs/Packages()?$filter=tolower(Id) eq 'ravendb.client'&$orderby=Id HTTP/1.1
DataServiceVersion: 1.0;NetFx
MaxDataServiceVersion: 2.0;NetFx
User-Agent: NuGet/2.7.40911.225 (Microsoft Windows NT 6.2.9200.0)
Accept: application/atom+xml,application/xml
Accept-Charset: UTF-8
Host: nuget.it.unistreambank.ru
Accept-Encoding: gzip, deflate

In response proget sends list of package versions but there is no requesed 2.5.2700. It lists 40 versions from 1.0.531 to 1.2.2005. While there are versions earlier than 1.0.531 and greater than 1.2.2005:
https://www.nuget.org/packages/RavenDB.Client/2.5.2700

Thanks for the additional debugging information; we now see why this doesn't work. It would appear that NuGet stopped streaming all versions of the packages at some point, and now appends the following at the end of its package search XML...

<link rel="next" 
href="http://www.nuget.org/api/v2/Packages?
$filter=tolower(Id)%20eq%
20'ravendb.client'&$orderby=Id&
$skiptoken='RavenDB.Clie
nt','RavenDB.Client','1.2.2005-Unstable'" /> 

So, we will need to add support for this as well... I've added this as PG-140, but it's not scheduled for a release yet. If an enterprise (i.e. paying) user requests this, we can expedite it of course.
