Node.js & MySQL - Error: 1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client

Question

Right now I have only this code:

const Sequelize = require(\'sequelize\');
const sequelize = new Sequelize(\'database\', \'root\', \'passwd\', {
  host: \'localh         


        

Answer 1

I found out that I was caused by incorrect parameters.

{ database: 'abc',
  username: undefined,
  password: 'efsefs',
}

username is undefined, but the error is "consider upgrading MySQL client" So modify the user name to be true, the error resolved.
