Topic specific page not opening about 450-dsa

@MeeeCoder do you mind connecting with me on telegram , i can take a closer look at the problem

The problem was fixed by going to the topic page and changing 450dsaversion in local storage from 100000005 to 100000000 and reloading right after.

(downgrading the version number will trigger an indexDB update and reload the data belonging to the latest 450dsaFinal.js version)

Yes this is a temporary fix, for now, hope I find a permanent fix for this fast 😓

@HackProAIT thanks for joining in and sharing your problem this can be fixed by clearing the localstorage of the browser for the 450dsa.com website and reloading the page

@avasthiabhyudaya this solution will not show your progress in incognito mode and resetting the localversion in local storage is a permanent fix.

@AsishRaju you're right, this is only for a way to get around this issue, so that we're able to do the questions whilst figuring out the problem with the app, like i did some practice today by using incognito, we can go ahead and check the boxes later as well.

[avasthiabhyudaya]

it has started working for me @AsishRaju

[harshrai654]

Now I can access the topic-wise page without any issues.

[AsishRaju]

@harshrai654 is this your local instance or 450dsa.com ?

[HackProAIT]

yeah same for me on 450dsa.com

yes i have observed something similar, whilst doing trees, maybe it has something to do with the progresss bar.
one way to get around this is right clicking the particular topic specific page and opening it in incoginito window.

[preet376]

When I clicked on Linked List, that topic page is not opening.

@AsishRaju what change did you make?

[AsishRaju]

@avasthiabhyudaya implementation of notes feature introduced new field Notes in 450DSAFinal.js that field was not applied to every question because setInterval i wrote which would reload the page before the function would have done its job, hence this error popped up.
We tried async and await but it didn't work and it was hard to reproduce this problem to know the exact cause, thanks to few of you for sharing there progress.json, i could debug the problem causing it.

What i did to fix this:

• Added bunch of undefined and null checks and increased setInterval() ms

Note:

This problem was not there for every user 🤷🏻‍♂️
