Notarization fails for the same app that used to succeed with errors

Notarization fails for the app which used to succeed 2 weeks back. Earlier I used to get log with ticketcontents along with warning message. This was expected as we do not adhere to notarization prerequisites. But now it fails with same messages, but warnings are marked as error in notarization log. Has anything changed after catlina official release, I thought prerequisites where relaxed until Jan 2020.
