Flagging Objects From Maya

Hello everybody

I am totally new on panda3d but I am not finding the solution for this scripts on maya2016.
I am trying to generate the MELscript for eggObjectFlags() but it generates only

“Cannot find procedure eggObjectFlags”.

I already drag and drop the name eggObjectFlags() and already generate the code on the script but it did not work.

Any advice?
