ProtocolViolationException in Octopus.Client When Adding Variable

[Tyler]

I am trying to programmatically add variables to a variable set and getting an exception:

ProtocolViolationException
You must write ContentLength bytes to the request stream before calling [Begin]GetResponse.
at System.Net.HttpWebRequest.GetResponse()
at Octopus.Client.OctopusClient.DispatchRequest[TResponseResource](OctopusRequest request, Boolean readResponse)
at Octopus.Client.OctopusClient.Update[TResource](String path, TResource resource, Object pathParameters)
at Octopus.Client.Repositories.BasicRepository`1.Modify(TResource resource)

at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
at System.Threading.ThreadHelper.ThreadStart()

This is the code I am using:

var server = "http://octopus.somewhere.com";
var apiKey = "API-xxxxxxxxxxxxxxxxxxxxxxxx";

var endpoint = new OctopusServerEndpoint(server, apiKey);
var clientFactory = new OctopusClientFactory();
using (var client = clientFactory.CreateClient(endpoint))
{
	var octopus = new OctopusRepository(client);

	var libraryVariableSet = octopus.LibraryVariableSets.FindByName("Our Set Name");
	var variableSet = octopus.VariableSets.Get(libraryVariableSet.VariableSetId);

	var variable = new VariableResource()
	{
		Name = "TestName",
		Value = "TestValue",
		IsEditable = true,
		IsSensitive = false,
	};

	variableSet.Variables.Add(variable);
	var result = octopus.VariableSets.Modify(variableSet);
	result.Dump();
}

I am able to connect, retrieve and display the variables without issue.

Thanks for your help!

Hi Tyler,

I’ve tried running your script locally and it’s working for me. Could I check which version of server and Octopus.Client you are using?

Could I also check whether you have any proxy requirements or anything like that on your network?
