HP SM 9.5 - Error while creating an operator

Hello Experts,

I am getting follwoing error while adding an operator, not sure about the exact root cause. Please could you help to reolve this.

Insert cancelled by trigger (se.base.method,add.record.radd)

 

while checking on messages it says 'You are not allowed to have a null password. Please try again.', but while creating a contact didnt find password field so while importing as well there is no password field then for what reason this message is being populated on the screen, need to know.

Let me know if any details are required to share.

Please advice, Thanks in Advance!
