May I know what you are trying to archive?
activityConfigs parameter is for your workflow actions configuration. You can get the activityConfigs value from your exported NWF. Upload your NWF by using this tool XML:Wrench :: online XML editor , and then select the text from <ActionConfigs>...</ActionConfigs> from the textbox.
Thank You for response. I would like to publish workflow on admin user who have more permissions, because i use in workflow option with "Run as workflow owner".
