Pls i want to confirm are you saying you also encountered the cast to objectid failed error at the activity page around the 4:49 hr mark or at another place because its getting really frustrating

I had those errors too. The password for Atlas and Mongo configuration file must be the same. Go to .env and make sure it matches the one on the Atlas browser configuration password.

send your github link I will check the error

this is the link: https://github.com/WelldiusPrimeX/socialmediaapp.git

send your github link I will check the error

Everytime I try to open create thread it takes me back to onboarding. please help

my onboarding page is showing error Property 'username' does not exist on type '{}'
and it is showing in every userData that i have created

you need to update your middleware.ts using clerkMiddleware, instead of authMiddleware

import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server'

const isPublicRoute = createRouteMatcher(['/sign-in(.*)', '/sign-up(.*)']);


export default clerkMiddleware((auth, request) => {

  PublicRoutes: ['/','/api/webhook/clerk']
  ignoredRoutes: ['/api/webhook/clerk']
  
  if(!isPublicRoute(request)) {
    auth().protect();
  }
}, { debug: true });

export const config = {
  matcher: ['/((?!.*\\..*|_next).*)', '/', '/(api|trpc)(.*)'],
};

works well on my system

I did use clerkMiddleware given in the documentation but it still is taking me back to onboarding, and my database is giving false on onboarding. I have commented these two lines i my code and now it shows threads so i am working with this temporary solution.

Does anybody else have a problem where the communities that are created, aren't being saved in MongoDB? My webhook is also going crazy with just saying attempting for each event:


Sorry if this is vague, just curious if other people have had the same problem
I am also facing the same issue. Did you find any solution ?

I did find a solution! I entered the wrong link for the deployment endpoint from vercel. Go on vercel and grab the deployment link and not the link from when you go to the deployed site in the search bar

how did you fix it? he used the browser link in the video right?
i tried the deployment link as well but it did not work

does anyone know why do I get this error by uploadthing, but when I check the uploadthing dashboard I do have the uploads there

UPDATE: I solve it

Hey can anyone help me with this error

Its cool I solved it.
