Profile Page Displays 404 Error for Unauthenticated Users

[kritikarma2007]

When a user who is not logged in clicks on the Profile section, the application navigates to /profile/undefined and displays a raw 404 error message.

This creates a poor user experience, as users are shown a technical error instead of being guided to log in or create an account.

Steps to Reproduce
Open the application without logging in.
click on Browse questions then
Click on Profile from the sidebar.
Observe the 404 error message on the profile page.
Expected Behavior

The application should detect that the user is not authenticated and display a user-friendly message or redirect the user to the login/signup page.

Actual Behavior

The application navigates to an invalid profile route and displays:
"Error loading profile: Request failed with status code 404"

Screenshot

Attached the screenshot showing the error state.

Hi Maintainers,

I found this issue while testing the application and would like to work on it under GSSoC'26.

I have identified the cause and can implement proper authentication checks along with user-friendly error handling.

Kindly assign this issue to me.

Thank you!
