Font issue with Savings Transactions when using a Fineract Docker image

[juandelcid]

Hello, I am using docker-compose.yaml from https://github.com/apache/fineract. I modified it to add this plugin and I can view transaction receipts (Savings Transaction Receipt.prpt). I then tried the Savings Transactions report (Savings Transactions.prpt) and it says something about fontconfig:

... 211 common frames omitted Caused by: java.lang.RuntimeException: Fontconfig head is null, check your fonts or fonts configuration

Which fonts should I add to the Docker image? Or, should we edit the report to work with the fonts available in the current Docker image?

Attached is the full stack-trace:
