Error with delete operation

I’m using confd v7.3 with rollback set to true.
I’m able to create configuration using edit-config with netconf-console.
However, when I try to delete the configuration, I get the following error and commit fails -

22-Apr-2020::18:59:10.631 test confd[26461]: - Error while creating rollback file: /opt/confd/var/confd-cdb/rollback0.prepare: Internal error

application operation-failed error Internal error

The rollback0.prepare file has only first line of the configuration written to it.

Can you please help me debug this further?

Best,
Vishal

This internal error is likely a ConfD defect. I would suggest to capture the steps for reproducing the issue along with all the log files and send them to your Tail-f support contact.

You can also try to post the YANG model part involved, relevant confd.conf parts, and config you used in your <edit-config> here for a sanity check by the community.
Post the developer log with log level set to “trace” too.
