Issue

  • ONTAP is not returning compression data for some volumes via REST API when it is requested by AIQUM.

  • Error seen in au.log:

ERROR [common-pool-4897] c.o.s.a.d.n.b.r.g.n.GClusterBuilder (GClusterBuilder.java:251) - [netappfoundation] dtnabbn01.dealertire.com - ExecutionException encountered on Builder java.util.concurrent.ExecutionException: java.lang.NullPointerException: Cannot invoke "java.lang.Long.intValue()" because the return value of "org.json.simple.JSONObject.get(Object)" is null java.lang.NullPointerException:* Cannot invoke "java.lang.Long.intValue()"* because the return value of "org.json.simple.JSONObject.get(Object)" is null

  • This can lead to the cluster polling operation state getting stuck "In Progress" / "Failed"
