Getting error while resizing image php codeigniter

I searched a lot but can't find out a solution for this problem actually I am trying to resize a image using codeigniter img_library. For resizing I am using this code. I am converting a base 64 encoded image using this code

$imgdata=base64_decode($image);
$imagename=$t.$s.'.'.$type;
$url= $target_dir.$imagename;
file_put_contents($url,$imgdata);         
$this->do_resize($url,$imagename);//calling the function to resize 



public function do_resize($url,$imagename){
   
    $source_path = $url;
    $target_path = base_url(). '/assets/test_images/'.$imagename;
    $config_manip = array(
        'image_library' => 'gd2',
        'source_image' => $source_path,
        'new_image' => $target_path,
        'maintain_ratio' => TRUE,
        'create_thumb' => TRUE,
        'thumb_marker' => '_thumb',
        'width' => 150,
        'height' => 150
    );
   
    $this->load->library('image_lib',$config_manip);
      $this->image_lib->initialize($config_manip);
     
      echo $this->image_lib->display_errors();
    if (!$this->image_lib->resize()) {
        echo $this->image_lib->display_errors();
    }
   
    $this->image_lib->clear();
}

and the error I am getting is this
