Attempt to read property "budget" on null

I'm having this issue where it throws this error on this piece of code

        $project = Project::find(request()->route()->parameter('project'));
        $budget = (int) $project->budget;

        $project = Project::find(request()->route()->parameter('project'));
        $budget = (int) $project->budget;

The property budget is not null and is read. if I

dd($budget)

dd($budget)

it shows the correct value if I

dd($project)

dd($project)

it shows obviously

Guessing the code gets triggered again without the request parameter being present. Don’t dd, but log and see what happens.

if you're on loop, please check all your data (maybe your dd only check first data)

Since it's getting null back from the query, it means it couldn't find the record by that id. So you could also try determining what it was searching for:

$project = Project::find(request()->route()->parameter('project'));
+ if (is_null($project)) dd(request()->route());
$budget = (int) $project->budget;

$project = Project::find(request()->route()->parameter('project'));
+ if (is_null($project)) dd(request()->route());
$budget = (int) $project->budget;
