consider upgrading mysql client mysql 8 uses an authentication method that is not supported by yet solution use the mysql native password plugin to make the account fall back to the "traditional" process during the handshake, keeping compatibility by default for any previously supported server version create the account using the mysql native password authentication plugin create user 'new user'@'%' identified with mysql native password by 'user password'; or, modify the existing user account, and specify the mysql native password authentication plugin alter user 'root'@'localhost' identified with mysql native password by 'yourrootpassword'; (reference https //github com/mysqljs/mysql/issues/2046#issuecomment 396039909 ) error er lock wait timeout lock wait timeout exceeded; try restarting transaction this error occurs when you modify the same data using multiple modules it is caused by sql transactions when any mysql module is executed, then it starts the transaction (1), and the transaction is finished after the is fully executed if another module tries to access the same data used in another unfinished transaction (1), then it has to wait until the previous transaction (1) is finished this, however, never happens because the first transaction (1) will be finished when the is finished solution turn on auto commit it finishes (commits) every transaction immediately after the module execution is done open the settings enable the auto commit checkbox click ok to confirm the settings
