We have mirror database in our network and master database in another network. We are getting the error "svnsync: E020014: Failed to find label 'NULL' for URL '/svn/MyRepo/!svn/rev/37'" in between during sync the mirror via https protocol(Internet).
If I'm running the command again, it's start syncing the revisions. Again we are getting the same error after some time. Can anyone help to resolve this error ?
You use a very old and unsupported version of VisualSVN Server. You need to upgrade to the latest version and see whether it helps. Contact [email protected] if the upgrade does not help resolve the issue.
Read the article KB138: Upgrading to VisualSVN Server 3.9 before beginning the upgrade.
