Hello,

log4j2 version that you have on classpath is incompatible with the version Tjahzi was compiled against. Tjahzi was compiled against 2.17.2 and method getPropertyArray is present in log4j2 since year 2018 (since version 2.12.2 of log4j2 but I might be wrong about exact one). Please check which version of log4j2 is in use and let me know if you think it is the correct one.

Longer explanation of the error: This error indicates that at runtime class LokiAppenderBuilder did not have a method getPropertyArray. That metod is part of log4j SPI and defined in class AbstractFilterable which LokiAppenderBuilder indirectly extends.

I have changed the version of Log4j to 2.17.2 , but the same error still appears.

I'm sorry but I have no other ideas. Definitely there is a mismatch between compile time and runtime version of the class. Maybe you can share the class path? You could also run this code when you app starts to verify where AbstractFilterable comes from:

System.out.println(
    AbstractFilterable.class.getProtectionDomain().getCodeSource().getLocation().getPath()
);
