Got GLib-GObject-CRITICAL **: g_type_class_unref: assertion 'g_class != NULL' failed from laravel php controller

I have a file container encrypted via VeraCrypt in a USB flash drive, and I have a Web App based on the LAMP stack and under Laravel framework. Now, I want to mount the encrypted file via the laravel php controller like this:

$cmd = 'veracrypt -p "longlongpassword" /media/username/usbName/encryptedFile /media/veracrypt1'; $process = new Process($cmd); $process->run();

but got an error message says: "GLib-GObject-CRITICAL **: g_type_class_unref: assertion 'g_class != NULL' failed"

However, if I run the command

veracrypt -p "longlongpassword" /media/username/usbName/encryptedFile /media/veracrypt1

from Ubuntu terminal, then it is successfully done without any error.

Can anyone give some suggestion about how to solve this issue? Thanks.
