K2 Cloud for Sharepoint Application Registration Wizard Error: "Response Null"

This article was created in response to a support issue logged with K2. The content may include typographical errors and may be revised at any time without notice. This article is not considered official documentation for K2 software and is provided "as is" with no warranties.

An issue occurs when trying to run the registration wizard, and you receive the following error:

"Response Null"

This stops you from proceeding further. You may see that a few applications are still accessible and still working as expected, however some applications that you may try to access via site collections will show you the following message:

“There is a new version of the K2 app, please do run the registration wizard........"


If you have recently upgraded to K2 Five and choose to remove the old K2 Blackpearl Application, this scenario can occur upon your environment, as the App ID’s do not change on the back end SQL tables:  [Integration].[ProcessSharePointGeneralSetting].

Troubleshooting Steps

A script will need to be obtained from the labs team to update the App ID. The App ID can normally be found within the registration wizard URL.

Please contact K2 support if you run into this issue as modifications will have to be made on the back end.
