MID Server logfile error: java.lang.IllegalArgumentException for mid.instance.username after upgrade - Support and Troubleshooting

MID Server logfile error: java.lang.IllegalArgumentException for mid.instance.username after upgrade Issue Problem The MID Server logfile displays the error: java.lang.IllegalArgumentException: Setting: mid.instance.username is not a legacy setting and is not supported by this API after MID Server is upgraded.

Release Australia

Cause 1. The mid server script include attempted to access the 'mid.instance.username' parameter using Packages.com.service_now.mid.MIDServer.get();

2. The upgrade introduced changes to MID Server configuration parameter handling, requiring the use of typed ms.MIDConfigParameter objects instead of bare strings.

Example:

var m= Packages.com.service_now.mid.MIDServer.get(); var config = m.getConfig(); var res = config.getParameter('mid.instance.username');

Should be replaced with var rest = ms.getConfigParameter( 'mid.instance.username' ); Resolution Steps to Resolve 1. Ensure the script include uses the supported method of retrieving parameters via the MID Server object (`ms.getConfigParameter` instead of direct string manipulation with Packages.com.service_now.mid.MIDServer.get(); ). 2. Test the data import functionality to confirm the issue is resolved.
