shell script prompting for password but not taking it while doing tar

In my shell script, I have following lines:

function tarIt() {
  FILE_OWNER=$1
  TAR_FILE_NAME=$2
  FILE_NAME=$3

  su - $FILE_OWNER -c "tar -cvzf $TAR_FILE_NAME $FILE_NAME > /dev/null 2>&1"
  if [ ${?} -ne 0 ]; then
      print_error "Failed to create backup.";
      exit $E_FAILED_COMPRESS;
  fi
}

While debugging, I am getting below lines:

+ su - ssrun -c 'tar -cvzf /tmp/backup/statusService/probe.properties.tar.gz /opt/mgtservices/probes/conf/probe.properties > /dev/null 2>&1'
Password: ssrun1
su: incorrect password
+ '[' 125 -ne 0 ']'
+ print_error 'Failed to create backup.'

I don't know while prompting for password, why my text is visible and password also it is not taking. The password is correct, when I copied the same line on command prompt, it executed without any error.
