Issue

When attempting to configure the K2 for Sharepoint App following the normal procedures to run the registration wizard first, you see the following error on the Application step:

"Response Null"

This stops you from continuing on with the initial configuration. 

Symptoms

The full error that is seen during the registration wizard is the following:

RESPONSENULL Type:

SourceCode.SmartObjects.Client.SmartObjectException Source: SourceCode.SmartObjects.Client Method Base Member Type: Method Name: ExecuteScalar Module Scope Name: SourceCode.SmartObjects.Client.dll Declaring Type Full Name: SourceCode.SmartObjects.Client.SmartObjectClientServer Stack Trace: at SourceCode.SmartObjects.Client.SmartObjectClientServer.ExecuteScalar(SmartObject smartObject, DataTable inputTable) at SourceCode.Forms.AppFramework.FormRuntime.SmartObjectExecution(BrokerSmartObject brokerSmo, SmartObjectBrokerMetaData brokerMetaData, Boolean outputDependencies, SmartObjectClientServer smoClientServer, Queue`1 soInstances) at SourceCode.Forms.AppFramework.FormRuntime.WorkXmlToApi(BrokerPackageCollection packages, SmartObjectClientServer smoClientServer) at SourceCode.Forms.AppFramework.FormRuntime.WorkXmlToApi(Stream input, Stream output) at SourceCode.Forms.Runtime.AJAXCall.ProcessRequestInternal(HttpContext context)

Troubleshooting Steps

This issue can occur due to there being old group providers within the K2 database

These can be cleared out via the K2 Management page > Users > SharePoint. From here you should be able to clear them out.
