exception in queueing Connect-Rest ,Database rollback caused queue item rollback

Hi

I am queueing a rest service as we are not concerned with response and its a time and also to enhance performance. I have created a request processor and mentioned queued class as "System-Queue-ExecutionRequest-Connect-Default". But whenever I am queueing anything and checking the instance created I am seeing the following error below. Please suggest how to mitigate this issue?
