Caused by: java.lang.NoClassDefFoundError: com/firehunter/ump/auth/NmsAuth

Environment

Release : 20.3

Component : UIM - API

Resolution

uimapi is only fully supported when deployed to the OC robot. 

If there is a need to use uimapi on another system then a second instance of OC can be installed at another robot under the primary hub. As of UIM 20.3.3 the OC installer can be used to setup a secondary instance of OC.

Additional Information

The same problem happens with webservices_rest when deployed to the primary hub.
