Troubleshooting: Object Reference Error on the Workflow or Post Authentication Tab

Version Affected: All
 
 

Overview

Navigating to either the Workflow tab or the Post Authentication tab returns an "Object reference not set to an instance of an object" error instead of loading the page.

Cause

This is caused by an issue with one of: the realm's web.config, the MFC.WebApp.SecureAuth.dll file present in the SecureAuth0 application, or the page file for the affected tab (WebAdminWorkflow.aspx for the Workflow tab, or WebAdminComplete.aspx for the Post Authentication tab).

Resolution

Try the following in order until the page loads successfully:

1. Run an Update Web.config on the realm, to restore any settings that may be missing from the web.config.
2. If that does not resolve it, back up the existing MFC.WebApp.SecureAuth.dll file in D:\Secureauth\SecureAuth0\bin, replace it with a copy of the same file from the Template folder, then perform an IIS reset and try the Workflow or Post Authentication page again.
3. If that still does not resolve it, back up the affected page file — WebAdminWorkflow.aspx for the Workflow tab, or WebAdminComplete.aspx for the Post Authentication tab — and replace it with a copy from the Template folder.

Special Considerations

Before replacing the DLL, you may need to stop the Cloud Transport service temporarily, since that service can hold a lock on the DLL and prevent it from being replaced.
