I also encountered the said error, what I did first was to remove the mysql using npm remove mysql, then install the mysql2, then edit the server.js to change the mysql to mysql2 then after saving my changes I restarted the server, and the error is gone.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password'; 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

FLUSH PRIVILEGES;

"password" is that you have to change the password you already have or you will modify it for a new one

Try change the password as below:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'your new password'; 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your new password';
