            </on-error-continue>
        </error-handler>

I am getting the following error message since the queue is empty ther are no messages to retrieve

Message               : Failed to retrieve a Message. Operation timed out after 10000 milliseconds
Element               : docusign-message-reprocessing-reports-subflow/processors/1 @ wbg-itsen-docusign-connect:docusign-reports-reprocess.xml:16 (Consume)

</jms:consume>

  (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

i dont want this repetetive message to print in logs every time scheduler is trigger I just want to discard the flow if there are no messages in queue.

You said you wanted to disable logging with on-error continue, but you have provided a ss of your consume operation. Also it is better if you provide the xml snipped instead of screenshot. — Harshank Bansal

You mentioned that the objective of the question is to avoid an error but you didn't mention the error. Please add it to the question so we know which error exactly you are trying to avoid. — aled

@kushmagonna Have you tried unchecking the "logException" option in the "on-error continue" scope? — jarus

Your <on-error-continue> shows logException="true". Change to false to avoid this error log. This is the same as unchecking "Log exception" in the "On Error Continue" scope that was suggested by @jarus in the question comments.
