When a node is bootstrapped and joined a cluster as a non-voter and changes it's role to a voter, errors can occur while committing a new Raft record, for instance, if the Raft leader changes during this time. These errors are not critical and should not cause a node crash, as the action can be retried.

Backport: This issue occurs frequently and disrupts the CI workflow to some extent. Backports are needed for versions 6.1 and 6.2.
