BeforeCreate hook for postgre not hashing password using bcryptjs

const userModel = connection.define('user', {
user_id: {
  type: Sequelize.BIGINT,
  primaryKey: true,
  autoIncrement: true
},
user_name: {
  type: Sequelize.STRING,
  unique: true
},
email: {
  type: Sequelize.STRING,
  unique: true
},
password: {
  type: Sequelize.STRING
}
},
{
hooks: {
  beforeCreate: () =>{
    console.log("hook called");
    return new Promise((resolve,reject) => {
      const salt = bcrypt.genSalt(10);
      const passwordHash = bcrypt.hash(userModel.password, salt);
      userModel.password = passwordHash;
      console.log('simple pass', userModel.password);
      console.log('hashed password', passwordHash);
      return resolve(userModel);
    });


  }
}
});

It returns this error. hook called simple pass Promise { } hashed password Promise { } Executing (default): INSERT INTO "users" ("user_id","user_name","email","password","createdAt","updatedAt") VALUES (DEFAULT,'deaehrddjelltariq','[email protected]','abcd','2018-02-15 00:17:51.272 +00:00','2018-02-15 00:17:51.272 +00:00') RETURNING *; (node:13686) UnhandledPromiseRejectionWarning: Error: Illegal arguments: undefined, object at _async (/Users/mfaisal/NodeProjects/chaffer/node_modules/bcryptjs/dist/bcrypt.js:214:46) at /Users/mfaisal/NodeProjects/chaffer/node_modules/bcryptjs/dist/bcrypt.js:223:17 at new Promise () at Object.bcrypt.hash (/Users/mfaisal/NodeProjects/chaffer/node_modules/bcryptjs/dist/bcrypt.js:222:20) at Promise (/Users/mfaisal/NodeProjects/chaffer/models/user.js:29:37) at new Promise () at Function.beforeCreate (/Users/mfaisal/NodeProjects/chaffer/models/user.js:27:14) at Promise.each.hook (/Users/mfaisal/NodeProjects/chaffer/node_modules/sequelize/lib/hooks.js:130:35) at tryCatcher (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/util.js:16:23) at Object.gotValue (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/reduce.js:155:18) at Object.gotAccum (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/reduce.js:144:25) at Object.tryCatcher (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/util.js:16:23) at Promise._settlePromiseFromHandler (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/promise.js:512:31) at Promise._settlePromise (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/promise.js:569:18) at Promise._settlePromiseCtx (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/promise.js:606:10) at Async._drainQueue (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/async.js:138:12) at Async._drainQueues (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/async.js:143:10) at Immediate.Async.drainQueues (/Users/mfaisal/NodeProjects/chaffer/node_modules/bluebird/js/release/async.js:17:14) at runCallback (timers.js:756:18) at tryOnImmediate (timers.js:717:5) at processImmediate [as _immediateCallback] (timers.js:697:5) (node:13686) UnhandledPromiseRejectionWarning: Unhandled promise rejection.

Replace your hook with this :

With the help of hashSync there is no need of promise 

beforeCreate : (user , options) => {
    {
        console.log("hook called");

        //const salt = bcrypt.genSalt(10);
        user.password = user.password && user.password != "" ? bcrypt.hashSync(user.password, 10) : "";

    }
}
