(error )Trying to get property 'id' of non-object laravel8 - html

Question

I am trying to store data by using id as primary key in Laravel 8, I used following code in controller :
public function store(Request $request)
{
$job = new Job();
$job->employeer_id = Auth()->user('employeer')->id;
$job->category = $request->category_name;
$job->job_context = $request->job_context;
$job->keywords = $request->keywords;
$job->title = $request->title;
$job->vacancy = $request->vacancy;
$job->deadline = $request->deadline;
$job->employment_type = $request->employment_type;
$job->location = $request->location;
$job->gender = $request->gender;
$job->age = $request->age;
$job->responsibilities = $request->responsibilities;
$job->education = $request->education;
$job->requirements = $request->requirements;
$job->additional_requirements = $request->additional_requirements;
$job->salary = $request->salary;
$job->benifits = $request->benifits;
$job->apply_instruction = $request->apply_instruction;
$job->save();
Category::where('category_name', '=' , $request->category_name)->increment('no_jobs', 1);
return redirect('/jobs');
}
The error says that :
Trying to get property 'id' of non-object
in this line :
$job->employeer_id = Auth()->user('employeer')->id;```

Answer 1

Instead of
Auth()->user('employeer')->id;
use
Auth::guard('employeer')->id();
or
auth('employeer')->user()->id;

Answer 2

Check if you get the user first
Auth::guard('employeer')->check();
Then put your code in condition if the user object exist.
So basically you should do this
if(Auth::guard('employeer')->check()){
$job = new Job();
$job->employeer_id = Auth::guard('employeer')->user()->id;
// rest of the code
}else{
// handle as you want
}
