Laravel - Using image intervention in Jobs. imagettfbbox error

Hi Im trying to use image intervention in my Jobs Controller. First, "image source not readable error" came out. But then I fixed by adding storage_path. Now it's showing this error:

Call to undefined function Intervention\Image\Gd\imagettfbbox() 

This happen when I want to write font on an image. These are my codes:

$img->text($line, $x_subject, $y, function($font) use ($font_size_subject, $font_path){
                $font->file(storage_path($font_path));
                $font->size($font_size_subject);
                $font->color('#000000');
                $font->align('center');
                $font->valign('middle');
            });

There is no error when I try to use it in normal controller. This error just shows up when I;m using image intervention in Jobs controller.

Is there any way I can solve this? Thank you
