Azure Cosmos DB - CreateDatabaseAsync - Resource Not Found

I have been developing an application with Azure Cosmos DB using the Emulator with good success - I've been able to create the database & collections and add documents to the collections as well as read those documents. the trouble now is that I've tried to swap the emulator out for a live instance of Azure Cosmos DB and I am getting an error whilst trying to create the database.
Microsoft.Azure.Documents.DocumentClientException: Entity with the specified id does not exist in the system.
note this is while trying to create the database not find it, the exact code is as follows
public async Task CreateDatabaseIfNotExistsAsync()
{
try
{
await client.ReadDatabaseAsync(UriFactory.CreateDatabaseUri(_databaseId));
}
catch (DocumentClientException e)
{
if (e.StatusCode == System.Net.HttpStatusCode.NotFound)
{
await client.CreateDatabaseAsync(new Database { Id = _databaseId }); // Throws Not Found Here!
}
else
{
Console.Write(e.StatusCode);
Console.ReadKey();
}
}
}
Any help would be greatly appreciated.
Edit
I have not connection string, only an endpoint and access key - I am connecting with
client = new DocumentClient(new Uri(_endpoint), _key);
I am targeting the DocumentDB API
the output of UriFactory.CreateDatabaseUri(_databaseId) is dbs/digivate_clients_0_blogging

Path between nodes query never finishes

I've created a graph in CosmosDB with two vertex types, an actor vertex and a movie vertex. The only edge type that exists is an "acted in" type. You can imagine the graph as having many actors and many movies and any given actor may have acted in any number of movies.
I am trying to write a query that will discover and return the path between two actors. For example, Keanu Reeves acted in the Matrix with Laurence Fishburn. Laurence Fishburn acted in the movie Apocalypse Now with Marlon Brando. Therefore, the path between Keanu Reeves and Marlon Brando is Keanu Reeves -> The Matrix -> Laurence Fishburn -> Apocalypse Now -> Marlon Brando.
This is the query that I've come up with.
g.V('keanureeves')
.repeat(both().simplePath())
.until(hasId('marlonbrando'))
.path()
.limit(1)
The query works for small graphs. I can query and construct the path. However, once I get to a certain graph size, the query times out and never finishes.
I am using the CosmosDB emulator locally, not the real CosmosDB on Azure. It's hard to say how many documents are in the database because the emulator UI doesn't give me a way to query for a count.
Can I speed up my query without changing my data model? If I do have to change my data model, what might work better? I'm new to graph databases and Gremlin.
Edit: It seems to happen between 1200 and 1300 documents. Under 1200 documents, results return. Here's the breakdown of document types:
540 movie vertexes
112 actor vertexes
681 actedIn edges
Edit #2: I'm using the Microsoft.Azure.Graphs NuGet package and it looks like the method I'm invoking is throwing an OutOfMemory exception. My code:
public async Task<IList<T>> ExecuteQueryAsync<T>(string gremlinQuery)
{
var query = _documentClient.CreateGremlinQuery(_graph, gremlinQuery);
var results = new List<T>();
while (query.HasMoreResults)
{
var feed = await query.ExecuteNextAsync<T>();
results.AddRange(feed.Select(x => x));
}
return results;
}

How can I handle and ignore these exceptions by exception filter? Why this error occurs and how can I reproduce that? I wanna catch and ignore only The client disconnected but not all HttpException
I saw this similar question but how can I do that in exception filter?

You can ignore these exceptions.
The exception says what the problem is: "The client disconnected". It means that the client initiated a request but then disconnected before it bothered to read all of the response.
There are any numbers of reasons why that might be the case, but (unless you have a dodgy internet connection at your server end) it is almost certainly an issue at the client end. I regularly see these myself and mostly it seems to be related to a bot. So I filter them out and ignore them.

try
{
// Open Connection
// Do stuff
}
catch (HttpException ex)
{
// Log it?
// Ignore it?
// Do what you want with it?
}
finally
{
// Close connection
}

Finding cause of object disposed exception with OWIN

Our company is using OWIN with ASP.NET MVC 5 and one of our developers is getting the following stacktrace at seemingly random times; however, I cannot reproduce the issue. I'm using SimpleInjector, but don't think this is related to it even though that line 118 in the stacktrace is the following:
app.Use(async (context, next) => {
using (container.BeginExecutionContextScope())
{
await next();
}
});
The other suspicious part is the reference to this in the stacktrace
Microsoft.Owin.Mapping.MapWhenMiddleware
I have a MapWhen configured like this
app.MapWhen(c => c.Request.Path.StartsWithSegments(new PathString("/api/mobile")),
api =>
{
ConfigureBearerApps(api, ValidateMobileIdentity);
});

Is there any additional logging I can enable to find the cause?

Most likely, you've implemented IDisposable on the object you're injecting, and then somewhere, you're calling Dispose on it. When using dependency injection, the container owns the instance and is responsible for disposing of it. The code you've posted doesn't provide any guidance as to where this might be occuring, so I would simply do a search for Dispose in your project and step through the results until you find something suspicious.
