Map export is stuck in the queue when we select the export option as Current Diagram and lower levels. For a single diagram it works fine.
 

Production and Test

Map export for option current diagram and lower levels are stuck in queue because it needs a Diagram render server and also Batch server to perform this task. (If you are getting an error as "unknown error is occurred " please follow this Article https://support.tibco.com/s/article/Diagram-Rendering-Service-Summary to configure Diagram render server)

Please follow the below steps to configure Diagram render server URL in the Batch Server configuration file.
1) Go to Tibco Nimbus Installation directory --> Batch Server
2) Open CtrlBatchServer.ini file in Notepad
3) In the [NimbusServices] section configure the URL (E.g: http://<servername>:3000/)
DiagramRenderServiceURL=http://mycomputer-name:3000/

Restart the services and try to export. (Please make sure Batch server and Diagram Render Service are running) and try export now.
