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.


The issue is when you look at the viewflow of the process instance via the K2 management page, the following error: "401.2 Viewflow error" occurs.


This happens when you install an environment with K2 blackpearl + K2 smartforms IIS Sites split and then upgrade to 4.7. The issue occurs when going to the view flow via the K2 management page.


This is a known bug, but please have a look at the following workaround:

Under the environment library node within workspace via the management tab the following must be added as a new field:

Name: Web Service URL SSL

Value: [WorkspaceURL]

Field Type: Web Service URL

Checked as default.
