Cannot read property 'slice' of undefined

const mysql = require("mysql2/promise");

var mpool = mysql.createPool({
  connectionLimit: 10,
  host: process.env.MYSQL_IP,
  user: process.env.MYSQL_USER,
  password: process.env.MYSQL_PASSWORD,
  database: process.env.MYSQL_DB,
});

async function getSomething() {
    const [rows, fields] = await mpool.execute(
        `select query`
      );
    console.log(rows);
}

query never runs and outputs this error below. isql is working with same login settings:

node_modules/mysql2/lib/auth_41.js:78 const authPluginData2 = scramble2.slice(0, 12);

                                ^

For something that was released 17 years ago, I would say not a lot 😂

we don’t have to support every old server version, but I think good behaving driver should not 1) crash when server version is not supported 2) return good error explaining what happened and how to fix

re particular version ( 4.1 and older ) - not sure how many people use it. I’d say not enough to justify dev effort but don’t have evidence to support. There is always drop in mysqljs/mysql replacement for those who must use old server
