Getting NullPointerException in server logs as WARNING while creating root application module Config

KARTIK PAPPUJun 1 2020 — edited Jun 1 2020

Hi,

Can you please help to found the root cause of the following issue,

While trying to create root application module object getting NPE (NullPointerException) in server log as WARNING. As this is a warning will it impact to application or not?

String amDef = "com.poc.model.appModule.POCAppModule";

String config = "POCAppModuleLocal";

am = (POCAppModuleImpl) Configuration.createRootApplicationModule(amDef, config);

In application UI not getting any errors.

Server Logs:
