How to test

Try this query:

  environmentNodes(filter: { name: "JDP" }) {
    descendantTargets {
      doStartRecording(recording: {
        name: "foo",
        template: "Continuous",
        templateType: "TARGET",
        duration: 0,
        restart: true,
        metadata: {
          labels: [
            {
              key: "cryostat.io.topology-group",
              value: "JDP"
            }
          ]
        },
        }) {
            name
            state
      }
    }
  }
}

Unfortunately, the label key does not accept forward slash /... So, I am thinking of using a dot separate the last part.

Opps forgot to update tests. Looking into it now.

Looks like itests need updating

Test fix makes sense.

Error:  Failures: 
Error:    JmxSessionAuthIT.checkStatusForRecordingsQueryWithoutCredentials:121 
Expected: <427>
     but: was <200>

I think it is related to the thread local issue that you mentioned?

[andrewazores]

Yea, that's the same bug.
