    Error "The Workflow has ended unexpectedly" when workflow changes state

    Status: Validated

    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.
