Hi Tamit,
you will have to find out where mkdir is called inside your IS.
Are you using execOSCommand somewhere in your code?
Was this working earlier or not?
When it was working in the past: Where any changes to your environment?
Did you check permissions and space on your OS where the directory should be created?
There should be a more meaningful error message why mkdir did not succeed beside just mentioning “Failure”.
Regards,
Holger
