So it seems you are using MariaDB Global Transaction ID with
MASTER_USE_GTID=current_pos, and you forgot to do the duplicate ID removal
under `SET sql_log_bin=0`.

The easiest solution is probably to CHANGE MASTER TO
MASTER_USE_GTID=slave_pos. This should make the slave ignore the local
transaction and just connect to the master using the last replicated
position.

(current_pos tells the MariaDB server that you expect any local transactions
on the slave to also be replicated to other servers, hence the error.
current_pos is appropriate for an earlier master that is turned into a
slave, but not for a slave where local "fixup" transactions ended up in the
binlog).

Hope this helps,
