When trying to export a report to an Excel file, I get this error in UI and Logs:
2025-06-20 17:41:28,077 [ajp-nio-0.0.0.0-8009-exec-698] ERROR com.appiancorp.rest.shared.AppianExceptionMapper - Internal Server Error on REST API invocation.

in rule 'taskfilters' (called by rules 'tasks' > 'dashboard') :
An error occurred while executing a save: java.lang.InternalError: java.lang.reflect.InvocationTargetException (APNX-1-4198-019)
I've searched in the community for similar behavior and tried some suggestions, but the problem persists and no one has resolved it.

The line 832 in the logs says this: "Caused by: java.lang.RuntimeException: Fontconfig head is null, check your fonts or fonts configuration"
Would this help with your investigation?
You're right!, we're missing this configuration, once it get installed it works, Thanks you!get install fontconfig or sudo "yum install fontconfig" depending on your OS.
