无法通过claviska / SimpleImage PHP将转换后的文件保存到特定文件夹

Library Link: https://github.com/claviska/SimpleImage

I am using toFile to save an image. I want to write the image on the specific path as I can't write on the root of the project on my server.

I am using this code

$image->resize($thumbnail->width, $thumbnail->height)->toFile($imageFileName);

This exception comes

Exception: Failed to write image to file: in claviska\SimpleImage->toFile()
