BIGIQ and REST API issues

Hi Team

 

ran into a weird issue today , wondered if some one could help me. was trying to discover a device using BIG IQ , tried adding a device and selected the option update firmware , and then the issue started.

 

BIG IQ version : 4.5.0 (build 3.0.7310 )

 

BIG IP LTM : its a vcmp guest on a 2400 chassis, 2250 blade , running BIG-IP 12.1.2 Build 0.93.249

 

and now turns out none of the ltm module queries work,

 

example --- works but

 

--- does not work

 

below is the error I get for /ltm related queries

 

errorStack": [ ": ;, "at ;, "at ;, "at ;, "at ;, "at ;, "at ;, "at $000(RestServer.java:45)", "at $1.run(RestServer.java:215)", "at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471)", "at java.util.concurrent.FutureTask.run(FutureTask.java:262)", "at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:178)", "at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:292)", "at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)", "at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)", "at java.lang.Thread.run(Thread.java:745)\n" ] }

 

any help is much appreciated ,

 

PS : this is a HA pair and the other node was not attempted to discover using big iq and ltm module queries work fine on it

 

thanks in advance
