Answer 1

If you clearly read the errors message, it says you are trying to access title on a null object.This means that the following relation is null.

 $user->profile // returns null

A quick way of error handling this, is using the null coalescing operator. This checks if the first statement at any point returns null, if not it returns the first statement. Else it have a fallback to the second statement.

{{ $user->profile->title ?? 'user not found'; }}
