spring - I get NullPointerException when debugging spring app using eclipse on remote server

Question

I'm working on an app that using spring 4.3 and java ee 6 and runs on weblogic 12.4.2 with jdk 7 and oracle 11 database. I'm using eclipse for java ee developers 2020-06. When I run this app, Everything is ok. But when I debug this app remotely, I get nullPointerException in some points like spring late bindings or in this code.

int inputGridSize = ((AccrualBatchFilter) getFilterObject()).getGridSize();

Weblogic not managed by eclipse E.G, eclipse does not connected to weblogic through oracle Enterprise Pack For Eclipse. I know I may not provided enough details, please tell me if more information needed. Thanks very much.
