jibri/YT not quite working, help

Hi,
I have a jibri instance for YT which i thiink is nearly there, i get a ‘Live stream stopped’ audio message within jitsi which is progress.

I have 2400 lines of java warnings on jibri startup

The following warnings have been detected: WARNING: HK2 service reification failed for [org.glassfish.jersey.message.internal.DataSourceProvider] with an exception:
java.lang.NoClassDefFoundError: javax/activation/DataSource

which i;m not sure is the problem, error log ends with
2020-04-28 12:44:25.980 SEVERE: [1177] org.jitsi.jibri.api.xmpp.XmppApi.run() Error starting Jibri service : org.jitsi.jibri.util.CallUrlInfoFromJidException: Unable to extract call url info from Jid room@my.url

which i suspect might be more pertinent,
I’m not sure if the issue is with my jibri or with my jitsi config at moment

any help appreciated
