Saving multiple data from dynamic form in Laravel and Vue JS - laravel

Question

I have a dynamic form that successfully adds multiple rows by clicking on the add button. the problem is when I try to save data into the database it throws the below error.
{message: "Illegal string offset 'supplier_id'", exception:
"ErrorException",…} exception: "ErrorException" file:
"C:\xampp\htdocs\Bookstore\app\Http\Controllers\API\PurchaseController.php"
line: 87 message: "Illegal string offset 'supplier_id'" trace: [{file:
"C:\xampp\htdocs\Bookstore\app\Http\Controllers\API\PurchaseController.php",
line: 87,…},…]
and help will be highly appreciated
Code in the controller
public function store(Request $request)
{
$products = json_decode($request->getContent('myArray') , true);
foreach( $products as $product )
{
Purchase::create([
'supplier_id' => $product['supplier_id'],
'date' => $product['date'],
'totalAmount' => $product['totalAmount'],
'description' => $product['description']
]);
}
// return dd($myArray);
return response()->json($Purchase);
}

I found the solution
public function store(Request $request)
{
if ($purchases= $request->get('myArray')) {
foreach($purchases as $purchase) {
Purchase::create([
'supplier_id' => $purchase['supplier_id'],
'date' => $purchase['date'],
'totalAmount' => $purchase['totalAmount'],
'description' => $purchase['description']
]);
}
}
return response()->json();
}
