Commencez par la trace de la pile dans vendor/github.com/go-mysql-org/go-mysql/packet/conn.go et replication/binlogsyncer.go, puis suivez les points d’entrée de gh-ost dans go/binlog/gomysql_reader.go et go/logic/streamer.go. Reproduisez la commande avec MySQL 8 et identifiez pourquoi la transmission du binlog signale une séquence de paquets invalide ; le travail est terminé lorsque gh-ost peut se connecter et commencer la transmission sans l’erreur fatale.

We've been getting this error since having migrated from MySQL 5.7 to MySQL 8. What could be the issue? Any advice on what we can try to get gh-ost working again.
