php – Laravel:Call to a member function store() on null-ThrowExceptions

Exception or error:

I’m using Laravel to get the request file from postman, however it seems Laravel cannot identify the file I posted. Following is my code:

namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;

class ProductImageController
public function update(Request $request, $id)
        $path = $request->file('file')->store('images');
        $product = Product::find($id);
        $product->img_url = $path;
        return $product->save() ?
            response(["error_code" => 0, $product]) :
            response(["error_code" => 1]);

Postman request

How to solve:

add this to your method and check if there is any errors and check if form-data is selected in postman, Be careful with explicit Content-Type header. Better – do not set it’s value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data – do not forget about boudary field.:

public function update(Request $request, $id)
   $this->validate($request, [
      'file' => 'required|file'


I think you can try this:

if ($request->hasFile('file')) {
            $product->img_url = $request->file('file')->store('images');

Hope this work for you !!!


try to:
-Change Put to Post in postman also in your ROUTE
-add this validator to your controller :

  $validator = Validator::make($request->all(),[ 

        'file' => 'file|required'

    if ($validator->fails()) {
        return response()->json(['error' => $validator->errors()], 401);
