I've sent an image from client side(Angular) to symfony. The upload works fine with small size images but when I try to upload a big size one (more than 2.0 mb) it does not work and shows me this error:
The "" file does not exist or is not readable. in vendor/symfony/mime/FileinfoMimeTypeGuesser.php (line 52)
     $data = json_decode($request->getContent(), true);
     $uploadedImage=$request->files->get('mainIMG'); 
           /**
             * @var UploadedFile $image
            */
        $image=$uploadedImage;
        $imageName=md5(uniqid()).'.'.$image->guessExtension();
        $image->move($this->getParameter('avatar_dir'),$imageName);
