      Description

      Hi, I used following scenario:

      Tested on Ubuntu 18.04 desktop with -> 10.3.13-MariaDB-debug and 10.4.3-MariaDB-debug
      • Start given number of nodes - with my test 5 nodes with 10.3 Maria + 3.x Galera.
      • Stop node5
      • start node5 with 10.4 Maria + 4.x Galera.
      • Run mysqld_upgrade on node5

      After that for not losing node5 with DDL as described here -> https://jira.mariadb.org/browse/MDEV-18422

      I have created table on node5(10.4) as:

      CREATE TABLE `sbtest4` (
        `id` int(10) NOT NULL,
        PRIMARY KEY (`id`)
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1
      

      It is successfully replicated to other nodes.
      Then from node1:

      CREATE TABLE IF NOT EXISTS temp4 AS (SELECT * FROM sbtest4);
      CREATE TABLE IF NOT EXISTS temp5 AS (SELECT * FROM sbtest4);
      insert into sbtest4(id) values(1);
      update sbtest4 set id=15 where id=1;
      

      From node5 error log:
