the error message does not explain much. By tracking the progress we identified a domain that did not get the change (removing excess key and rolling over another because of a whitespace in the value in the registry db (#2036).

so maybe this one caused the error, but cannot be sure.

The domain has two dnssec public keys in the registry out of which one looks strange for elliptic curve key:

key1: (alg:13) mdsswUyr3DPW132mOi8V9xESWE8jTo0dxCjjnopKl+GqJxpVXckHAeF+KkxLbxILfDLUT0rAK9iUzy1L53eKGQ== (there is a space in there but its not showing up here)
key2: (alg: 13) 97F4C303B7D2EC36440B2EB337A5AF99662851CCA35F1653754D4DF3A8C50801 (looks like a hash instead of a key)

Fixed a typo in csync job by #2038 , now error message should be more informative.
