### Summary

Hi community, hope you are doing well,  
It has been 3 occurences where i submit plugins (developed by me) on Fab and receive a report of the need to review the plugins, where they send errors with code that have not been raised on my build, knowing that i did build the code and run it in my enviroment, and also there is a plugin that i used to build a project with and that one got a review for error fixing.  
Also i unable to recreate the errors sent by Fab team, so the fix is just based on the sent document.  
I would like to know what might be the Fab enviroment test build they are using to test assets?  
My enviroment is : Win 11, Unreal engine 5.7, Visual studio 2022 Version 17.14.30.

In case anyone have this same problem, and after contacting fab support they advised to use the following command:

Engine\Build\BatchFiles\RunUAT.bat BuildPlugin -Plugin=[Path to .uplugin file, must be outside engine directory] -Package=[Output directory] -Rocket
