ISSUE
When running a workflow, the workflow will enter the first state, however as soon as it tries to change state it will fail. The following error is logged in the workflow history:

The Workflow <name> has ended unexpectedly.

In ULS, the logs indicate the OWSTIMER.exe service on an Application server starting the workflow, and then failing.
ERROR CODE
RESOLUTION
  1. Locate a Web Front End server which has the Web Application service running.
  2. Open a SharePoint Management Console and run the following PowerShell command to copy workflow-related configuration from the web.config to the configuration database so it will be available from every server in the Farm.
    $webapp = Get-SPWebApplication -identity http:// $webapp.UpdateWorkflowConfigurationSetttings()
ADDITIONAL INFORMATION
This is caused by missing Workflow Manager config on the Application server.
