Crashing due to FD ownership violation

In the apps created using Nodejs & Electron, a “crashing due to FD ownership violation” error often occurs in the two scenarios :

1.Accessing a File which is not owned by the current user.

2.Accessing the printer installed with anonymous user.

This issue is basically of ownership of files and ownership of Installation of Printer Driver . If the electron app tries to access files or tries to print using the printer owned by different or anonymous user this problem will occur.

in Linux, file permissions and ownership are critical to security and performance. If the current user has no permission and ownership to the file or printer then the electron app will crash due to FD ownership violation.

To solve this issue do the following :

Files :

To solve this problem , assign ownership of the file to the current user .

sudo chown $USER your_file_name

Replace your_file_name with your actual file name if different.

Printer :

Install printer as root user and give permissions and ownership to the current user .

sudo chown $USER /dev/usb/lp0

Replace /dev/usb/lp0 with your actual printer device path if different.
