Business Process - Object reference not set to instance of object Error

Workflow
Updated February 5, 2015
asked on July 24, 2014

 

When starting a business process, we are getting an error shown below:

 

The BP has been validated and a starting rule is in place to enable the BP.  All metadata fields required are set as needed.  This error pops up shortly after you click start on the BP and the BP does not initiate - even to the first step.  Any ideas on where the problem lies?

This specific issue was resolved by going into IIS and modifying the authentication settings for the Workflow web application. Windows Authentication needed to be enabled (along with Anonymous Authentication which should already be enabled by default). Once that was done and IIS was reset, the business processes were republished through the Workflow Designer and users could then start business processes from the Client.

This usually shouldn't be needed, but was what was required to address the problem at this organization.

As an aside, please make sure that you've upgraded to Workflow 9.2.

Windows authentication was disabled. After enable and iisreset, the business processes work. 

 

Thank you for your help!

What is the name of the Workflow/Business Process? In the Workflow Designer, view the business process and under "Business Process Options" click on "More Options..." and change the Instance Name to "Use the following name:" while giving it a new/different name. Then republish and try again in the Client (after first closing and reopening the Client).

  1. Does the issue occur for all users (LF user, LDAP user, Windows user) that logs into the repository?
  2. Does the issue occur for all business process that try to be run?
  3. Does the issue occur for all documents that are trying to have the business process run on?
  4. Does the issue occur on all computers that have the Client installed?

 

Please let us know if you have any other information that may narrow the scope of the problem. Also, you can contact your Laserfiche reseller to open a support case as well.
