TypeError Illegal offset type vaildator for images mimes types

The following code will verify whether an image is a JPG, JPEG, or PNG.

I tried to upload a jpeg file, but the validator somehow throws an error.

 $validate = Validator::make($request->all(), [
            $request->file('image1') => 'required|mimes:jpg,png,jpeg',
            $request->file('image2') => 'required|mimes:jpg,png,jpeg',
            $request->file('image3') => 'required|mimes:jpg,png,jpeg',
            $request->file('image4') => 'required|mimes:jpg,png,jpeg',
          ]);
        //  dd($validate[0]);
         if( $validate->fails() ){
          return response($validate->errors(), 400);
         }

how the request appears It receives 4 photos and is supposed to verify whether they are images before uploading them to the server.

  }

The correct way to create the Validator would be to add the file names as keys https://laravel.com/docs/10.x/validation#manually-creating-validators

$validate = Validator::make($request->all(), [
            'image1' => 'required|mimes:jpg,png,jpeg',
            'image2' => 'required|mimes:jpg,png,jpeg',
           'image3' => 'required|mimes:jpg,png,jpeg',
            'image4' => 'required|mimes:jpg,png,jpeg',
          ]);
