This is my code for fetching the data from Firestore and using the data for populating my pages before rendering on web pages. This works fine when I am using in localhost before deployment, But after deployment on Vercel, it is taking too much time to render the pages on-screen and then shows request time out on screen. And an error in the function logs below:-

Some errors in function logs on Vercel:

Can anybody tell me why I am getting this error after deployment as it works fine before deployment. Below I am also attaching the link to the project https://chitzzapp.vercel.app/
