javascript - Req flash with delay in express 4 app -


i'm using passport js local strategy authenticate user webapp see delay setting flash message , try using {message : ''} option in passport , passing request function setting manually flash message delay persist :

    passport.use(new localstrategy({passreqtocallback:true},     (req,username,password,done)=>{     userbl.getuserbyusername(username).then((user) => {         if (user != null && user != undefined) {              if (password == user.password) {                 return done(null,user)             }             else {                 return done(null,false,req.flash('error','constraseña incorrecta'))             }         } else {             return done(null,false,req.flash('error','usuario'))         }        }); }));

and call error req.flash('error') empty , after second reload or time show's error , flash value , . thanks

it's normal delay req flash or error ?

according documentation http://passportjs.org/docs, should pass like

done(null, false, { message: 'incorrect username.' });

but seems you're handling error message using

return done(null,false,req.flash('error','constraseña incorrecta'))

which might cause kind of asynchronous issue think.
