Stephen Mallette closed TINKERPOP-2541.
---------------------------------------
Resolution: Invalid
As it seems as though there hasn't been any recent activity here, I'm going to
assume this issue to be one that is specific to CosmosDB and close it. We can
re-open if needed.
> .NET SDK (CosmosDb): The server returned status code '500' when status code
> '101' was expected.
> -----------------------------------------------------------------------------------------------
>
> Key: TINKERPOP-2541
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2541
> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet
> Affects Versions: 3.4.10
> Reporter: Kirk Marple
> Priority: Major
>
> Using 3.4.10, .NET SDK, I've been getting a lot of problems talking to
> CosmosDb lately.
> Some hangs on SubmitAsync (after several successful calls), and sometimes
> errors just creating the GremlinClient.
> Seems to have cropped more over the last month, where I can reproduce it more
> often now. I've tried playing with pool size, etc. and haven't been able to
> get around it.
> I'm able to repro it just from my laptop locally when running integration
> tests against CosmosDb.
> Any thoughts on this? It's preventing us going into production with our
> application.
