Hi Devs, I have verified this in WSO2EI 6.3.0 and I can see the same behavior. I have created a git issue[1] which contains the same API to test this. [2] is the exception that occurs for the sample and in that the ERROR CODE is 0. I have sent a PR [3] which handles this exception and sets the Error Code as 401003 (Non-Blocking Call Failure) and com.rabbitmq.client exception message as the Error Message.
