1. Install the NSS Library: On most Linux distributions, you can install the required NSS library using the package manager. Depending on your distribution, use one of the following commands. For other systems, refer to the dependency installation documentation for your operating system:

   • Ubuntu/Debian:

     sudo apt-get update
     sudo apt-get install libnss3

   • CentOS/RHEL:

     sudo yum install nss

   • Fedora:

     sudo dnf install nss

2. Check the Library File: After installing the dependency library, check if libplc4.so is in the system's library path. You can use the find command to locate this file:

   find / -name libplc4.so

After performing the above steps, try running the PDF and PNG export operations again. They should work successfully. If the issue persists, ensure compatibility between the system architecture and the relevant software versions.

Dashboard Subscription Screenshot and Web Display Discrepancy

The web preview shows 20 rows of data, but the exported PDF only displays 17 rows. As shown in the image below:

This issue is typically caused by the absence of fonts like Arial on the machine where the service is deployed. Installing the required fonts should resolve the issue.

Tip

The Arial font may involve copyright issues. Please ensure you have the appropriate usage rights.

CentOS Series Installation Reference

cd /usr/share/font/arial
mkfontscale
mkfontdir
fc-cache -fv

# Verify if the font is effective
fc-list | grep -i "arial"
