Prebotmodifier flag is not working

0

I 'm using robot framework version 3.2.1 i’m executing the robot with the prerebotmodifier flag

like this :

‘’’’ robot.run(‘Tests\Common\infraTest.robot’, variable=‘sut:new_sut_test_example’, listener=‘Tools/PublisherListener.py’,prerebotmodifier=‘Tools/premodifier.py’)

‘’’’’’

I have a file called premodifier.py with visit_test and visit_suite methods but when debugging i can see that the debugger doesn’t enter this file

what am i doing wrong ?
