Sign In Issue 403 type error access forbidden

Hello! Got an issue with sign in. Made several attempts to sign in but unfortunately every time got the same mistake " TypeError

403 res.redirectWithFlash is not a function".

I know that 403 code means access is forbidden, but I don’t understand why the access was forbidden? I have passed Responsive Web Design Challenges in September 2019, approximately several months ago I have started JavaScript challenges, yesterday everything worked fine, but today I got this issue. Does anyone know how to fix it?


I deployed a patch to address the heightened error rates with the API instances, we are also adding more servers to handle the load.

The sign in issue should be resolved now. Thanks for your patience and understanding.


Tell us what’s happening:

Your code so far

function getFinalOpenedDoors(numDoors) {
return numDoors =[{name:"door" , open:"true"}];
        var i;
        for(i=0; i<numDoors.length; i++){
                open: 'false';
// Good luck!
