I want to upgrade a plugin for the ServiceNow Studio but whenever I want to it keeps showing Internal Server Error (500).

 

I am also trying to upgrade the plugin on a self-hosted/on-prem instance.

Hi @js_schwarz 

 

Might be better to log a Now support case.

Hi @js_schwarz. For upgrading plugins on self-hosted instances, you may need to obtain a temporary instance login and password from ServiceNow Support. This will provide the maint role and enable you to install the plugin - but only if that plugin was available when you installed your on-prem instance.

For newer plugins, you will need to upgrade the instance to a newer patch level or a newer family (Yokohama instead of Xanadu, for example)
