OTM Data Purge Error Encountered

Hi All

I need your advice to know as to where I might be going wrong related to OTM Purge process:

• Need to purge data for GTM Transactions which older than 180 days & not modified.
• I created a saved query for the GTM Transactions older than 10 days and not modified on Test Instance for a test run.
• I logged into DBA.ADMIN domain. Ran the mark for purge process in process management of Configuration & administration module.
• Data type query object selected was GTM Transaction and saved query was selected and the process was submitted.
• In view logs there was an exception encountered mentioning 'query could not be retrieved'.

Please provide your suggestions to resolve the situation.
