Trying to get property of non-object for index.blade.php

<td>{{ $routeFEmail->id }}</td>
<td>{{ $routeFEmail->routeF->id }} ({{ $routeFEmail->routeF->vessel_name }})</td>

i did also
php artisan cache:clear
php artisan route:clear
php artisan view:clear

{
$routeFEmails = RouteFEmail::orderBy('id', 'desc')->paginate(10);
return view('backend.route_f_emails.index', compact('routeFEmails'));
}
HOW I CAN FIX THIS ? :(

Answer 1

Your problem is with compact(), Return type of compact() is array [Read Here], so when you are passing compact('routeFEmails') it is converting object to array.
In index.blade.php you are accessing values of $routeFEmails as object. So you can try one of below solutions.
Solution 1
Write <td>{{ $routeFEmail['id'] }}</td> instead of <td>{{ $routeFEmail->id }}</td>
OR
Solution 2
Write
return view('backend.route_f_emails.index', ['routeFEmails'=>$routeFEmails]);
instead of
return view('backend.route_f_emails.index', compact('routeFEmails'));

Answer 2

trying to get a property on a non object means that the $routeFEmail is not an object not that some of it's properties like id is null.
Also the part
$routeFEmail->routeF
could be null ( My guess that the problem is there)
you can skip it with
#if( !is_null($routeFEmail->routeF) )
write something
#endif
or even dd if it is null
