RavenDB4 'documentStore.Operations' threw an exception of type 'System.ArgumentNullException'

[oru malayali]

Hi,

After the document store is created and initialized,

the documentStore.Operations property shows the following in watch window:

'documentStore.Operations' threw an exception of type 'System.ArgumentNullException'.

Below is how I create the document store:

            var documentStore = new DocumentStore

            {

                Urls = new[] { connectionStr },

                Conventions =

                {

                    SaveEnumsAsIntegers = true,

                    FindCollectionName = type =>

                        typeof(ChangeProposal).IsAssignableFrom(type)

                            ? "ChangeProposals"

                            : typeof(PropertyDefinition).IsAssignableFrom(type)

                                ? "PropertyDefinitions"

                                : DocumentConventions.DefaultGetCollectionName(type)

                }

            };

Is there something wrong or missing in how I create it?

The version I am using is 4.0.3-patch-40031.

Thanks,

Lokesh

You are missing the Database property.

The NRE (in favor of an explicit error) has already been corrected in the latest code.

Also you need to call Initialize()

Hi 

Oren,

Is it compulsory to set the Database property when I create the document store? I will update the packages and try again.

Thanks.

Tal,

I am calling the Initialize, I missed that line of code here. Thanks.

Lokesh.

Hi Oren,

I got an ArgumentNullException when doing the following:

    session.Advanced.DocumentStore.Operations.ForDatabase(databaseName).Send(operation);

That is when the Database name is not set when creating the document store.

The following is the stacktrace:

   at System.Collections.Concurrent.ConcurrentDictionary`2.TryGetValue(TKey key, TValue& value)

   at Raven.Client.Documents.DocumentStore.GetRequestExecutor(String database)

   at Raven.Client.Documents.DocumentStore.OpenSession(SessionOptions options)

   at Raven.Client.Documents.DocumentStore.OpenSession()

   at Raven.Client.Documents.Operations.DeleteByQueryOperation`1.GetCommand(IDocumentStore store, DocumentConventions conventions, JsonOperationContext context, HttpCache cache)

   at Raven.Client.Documents.Operations.OperationExecutor.<SendAsync>d__11.MoveNext()

--- End of stack trace from previous location where exception was thrown ---

   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)

   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)

   at Raven.Client.Util.AsyncHelpers.<>c__DisplayClass3_1`1.<<RunSync>b__0>d.MoveNext()

--- End of stack trace from previous location where exception was thrown ---

   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

   at Raven.Client.Util.AsyncHelpers.RunSync[T](Func`1 task)

   at Raven.Client.Documents.Operations.OperationExecutor.Send(IOperation`1 operation, SessionInfo sessionInfo)

And when I set the Database to string.Empty, it works fine.

Btw, the operation is a DeleteByQueryOperation.

So, I guess the Database name cannot be null?! 

Thanks.

The database name _can_ be null (that was a bug that was recently fixed) 

But if it is, you'll need to specify which db in every call

[oru malayali]

I see. I am using the 4.0.3-patch-40033 version. 

Also, I am using the Operation.ForDatabase as you recommended before, when I have an operation to do, so that I am sure. 

I will wait for the next prerelease if the fix is in the Nightly.

Thanks a lot.
