Simplified code
When I put {{ $mea->cat }}
the view returns JSON and "slug" is present.
When I put {{ $mea->cat->slug }}
I have the error: Attempt to read property "slug" on null
WTF 🤪

Attempt to read property "slug" on null
Good morning, something really weird.
This code gives me the error Attempt to read property "slug" on null :
@php
// dd(url('cat/'.$mea->cat->slug.'/art/'.$mea->slug));
@endphp
<a href="{{ url('cat/'.$mea->cat->slug.'/art/'.$mea->slug) }}"> {{ $mea->titre }}</a>
If I uncomment "dd", it returns what I want:
"http://lfjp2.test/cat/etablissement-activites-periscolaires/art/les-activites-periscolaires-2023-2024" // resources/views/inc/alaune.blade.php
I'm on new Herd, Laravel 9 up to date, PHP8.2, all caches cleared. Relationships in models OK... I don't understand and can't find the solution :/

Are you looping over a Collection of records; perhaps the first item in the Collection has a cat instance, but another/others do not? Check using @dump directive rather than dd:
@dump($mea->cat);
{{-- <a href="{{ url('cat/'.$mea->cat->slug.'/art/'.$mea->slug) }}"> {{ $mea->titre }}</a> --}}

@COTIGA no worries, consider marking the thread solved if you are all set

@COTIGA Just remember that @dd will exit after the first time it's seen, so if the problem is in the third instance of a model, you might never get there. Whereas @dump prints the same info, but does not end the process so that if the problem is in a future instance, you'll be able to see it.
Both tools have their uses.

Have you done:
php artisan config:clear
php artisan cache:clear
composer dump-autoload
php artisan view:clear
php artisan route:clear
I have that saved in my zshrc like so:
alias nukelaravel="php artisan config:clear
php artisan cache:clear
composer dump-autoload
php artisan view:clear
php artisan route:clear"
And I run it as a first step when it behaves really strange. 50% of the time it works

@Brainmaniac Yes, but thanks for the alias, cool ;)

@Brainmaniac strange. I code multiple projects every week and never use any of those commands.
(maybe composer dump if I have changed the name of a class, but I know thats part of the process)
If you NEVER cache routes and config in dev, you never need to clear it.
