Submitting a form leads to log out - laravel

Question

Information:
Language: PHP
Framework: Laravel 9
Database: Firebase, firestore
I'm trying to input data from a form in a blade to firestore database. However, it doesn't add in the database. Also after clicking the submit button, it just redirect me to the login page. Basically, it log outs me without even having successfully adding the data input.
What I have tried so far:
as per #Aless55, there might be an error. I checked, there's none.
InventoryController:
public function store(Request $request){
$data = [
'SKU' => $request->invSKU,
'Product Name' => $request->invName,
'Stock' => $request->invStock,
'Date added' => Carbon\Carbon::now(),
'Last Update' => Carbon\Carbon::now(),
'Item sold' => '0',
'Status' => 'active'
];
$postData = $this->app('firebase.firestore')
->database()
->collection('Inventory')
->newDocument()
->set($data);
if($postData){
return redirect('admin.inventory');
} else{
return redirect('admin.inventory-add');
}
}
web.php:
//For Inventory
Route::controller(App\Http\Controllers\InventoryController::class)->group(function(){
Route::get('inventory/add', 'invAdd')->middleware('user','fireauth');
Route::post('inventory/add/product', 'store')->name('add.product');
Route::get('inventory/archive', 'invArchive')->middleware('user','fireauth');
});
form part of inventory-add blade:
<form style="padding-left: 0px;margin-left: -9px;" method="POST" action="{{Route('add.product')}}">
#csrf
<div style="display: flex;">
<div style="padding-right: 0px;margin-right: 29px;">
<h6>Name</h6><input class="form-control" type="text" style="padding-bottom: 0px;" name="invName" autocomplete="off">
</div>
<div style="padding-right: 0px;margin-right: 29px;">
<h6>SKU</h6><input class="form-control" type="text" style="padding-bottom: 0px;" name="invSKU" autocomplete="off">
</div>
<div style="padding-right: 0px;margin-right: 29px;">
<h6>Starting Stock</h6><input class="form-control" type="number" name="invStock" autocomplete="off">
</div>
</div>
<div style="display: flex;margin-top: 11px;">
</div><button class="btn btn-primary" type="submit" style="margin-top: 15px;text-align: right;margin-left: 397px;padding-right: 14px;background: #2f3192;">Submit</button>
</form>
middleware:
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Session;
class FirebaseAuth
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle(Request $request, Closure $next)
{
$uid = Session::get('uid');
if ($uid) {
return $next($request);
}
else {
Session::flush();
return redirect('/login');
}
}
}

Answer 1

I have this side menu and the logout part used to be like this
<li class="nav-item"><a class="nav-link" href="" onclick="event.preventDefault();
document.getElementById('logout-form').submit();"><span></span><strong style="font-size: 16.6px;"><img src="{{ asset('build/img/vectors/logout%20icon.png?h=dbf300e18e83c66a9b08989511fc388a')}}"> Sign out</strong></a></li>
<form id="logout-form" action="{{ route('logout') }}" method="POST" class="d-none">
#csrf
</form>
I removed the form and leave the {{ route('logout') }}
and my solution:
<li class="nav-item"><a class="nav-link" href="{{ route('logout')}}"><span></span><strong style="font-size: 16.6px;"><img src="{{ asset('build/img/vectors/logout%20icon.png?h=dbf300e18e83c66a9b08989511fc388a')}}"> Sign out</strong></a></li>
