Caused by: java.lang.IllegalArgumentException: Object name cannot be null
        ... 30 more

I think when combining the object name

            Set<ObjectName> set = mBeanServer.queryNames(new 
ObjectName(agent.getMBeanObjectDomainName() + 
":type=services,name=DefaultInflightRepository,*"), null);

The ":context=context-name" part is missing.
The query should be something like

org.apache.camel:context=<context-name>,type=services,name=DefaultInflightRepository

Not sure why the ",*" at the end would be needed.

You can do a log:display-exception to get more details.

Also what version of Camel, Karaf are you using. And does some of the
other karaf camel commands works?
