    Status: Pending Clean Up

    ISSUE
    When automating the installation and configuration of Nintex workflow using the nwadmin tool cmdlet NWAdmin-exe-o-ConfigureSettings the error below is displayed in the command prompt:

    Error Message: 
    Command line execution error: Value cannot be null. 
    Parameter name: Data Source
     

     
    ERROR CODE
    RESOLUTION
    Check the database section of the xml file being used for any invalid element. i.e.
    The issue could be as a result of an error in the definition of the elements under ConfigDatabase in the xml file. Sample section of xml file:

    <ConfigDatabase>
    <Database >
    <Server>SQLSERVERNAME</Server>
    <DatabaseName>NintexWorkflowDB_Config</DatabaseName>
    <UseIntegrated>true</UseIntegrated>
    <Username>User</Username>
    <Password>Password</Password>
    </Database>
    </ConfigDatabase>

    The issue lies within the <Database> elements which should not exist as defined in the NintexworkflowSetup.xsd. The presence of the <Database> elements makes the nested elements unreadable effectively causing the error. The valid definition for the Config Database should be as follows.
    <ConfigDatabase>
    <Server>SQLSERVERNAME</Server>
    <DatabaseName>NintexWorkflowDB_Config</DatabaseName>
    <UseIntegrated>true</UseIntegrated>
    <Username>User</Username>
    <Password>Password</Password>
    </ConfigDatabase>
