Works fine on my local machine. However, it fails when we run it on the CloverDX Server.

I have attached a simple graph that illustrates the problem.

Run it locally. It will run fine.  
Copy it to the server and run it. It will fail.

This request has been resolved via email.

Some linux machines miss a library required by CloverDX - fontconfig. Installing it did the trick:

```auto
apt install fontconfig

```
