why sequelize-cli is not loading config variables? - mysql

Question

I tried searching for the answer, closest question i got was Sequelize CLI Not Finding Env Variables.
I compared my code and it was exactly like the answer provided, then just to debug i edited config file to set values manually instead of reading from .env but sequelize-cli still gives same error
ERROR: SequelizeDatabaseError: Access denied for user ''#'localhost' to database 'dbname'

Here is my config.js file
require("dotenv").config();
console.log(process.env.NODE_ENV, "it is being loaded correctly");
const config = {
development: {
username: "mysql",
password: "",
database: "dbname",
host: "localhost",
port: "3306",
dialect: "mysql",
dialectOptions: {
charset: "utf8mb4",
},
},
production: {
username: "mysql",
password: "",
database: "dbname",
host: "localhost",
port: "3306",
dialect: "mysql",
dialect: "mysql",
dialectOptions: {
charset: "utf8mb4",
},
},
};
console.log(config);
module.exports = config;
and lastly here is .sequelizerc file
const path = require('path');
module.exports = {
'config': path.resolve('config', 'config.js')
}
Funny thing is this project was working perfectly on my last computer (macos) and my server(ubuntu) but i am facing this issue with ubuntu desktop. AFAIK it should not be an operating system problem.
here is models/index.js
"use strict";
require("dotenv").config();
const fs = require("fs");
const path = require("path");
const Sequelize = require("sequelize");
const basename = path.basename(__filename);
const env = process.env.NODE_ENV;
console.log(env);
const config = require(__dirname + "/../config/config")[env];
const db = {};
console.log("config check", config);
let sequelize;
if (config.use_env_variable) {
sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
sequelize = new Sequelize(
config.database,
config.username,
config.password,
config
);
}
fs.readdirSync(__dirname)
.filter((file) => {
return (
file.indexOf(".") !== 0 && file !== basename && file.slice(-3) === ".js"
);
})
.forEach((file) => {
const model = require(path.join(__dirname, file))(
sequelize,
Sequelize.DataTypes
);
db[model.name] = model;
});
Object.keys(db).forEach((modelName) => {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
UPDATE 1:
I have tried to connect to database programmatically and get same error.

Answer 1

A couple of shots in the dark: If you try to connect with a blank password you need to set the password param to null in the connection configuration:
const sequelize = new Sequelize('database', 'username', null, {
dialect: 'mysql'
})
Also, as mentioned in a comment, it looks like it can't set your username correctly, so it turns out as an empty string ('') in the error msg.
Maybe you have switched around username and password in the config object for Sequelize so the empty password becomes the username?
Will update this answer if I get better ideas when you show the connection code :)
EDIT 1:
Seems to be something fishy about your config in new Sequelize(process.env[config.use_env_variable], config);
It should have four parameters, here you have added the username and password into the config object. There should be three string params (or null) and one config object, four in total.
