SFT external monitor is failing wiht 'OSError: [Errno 2] No such file or directory'

Hi,

I have created new external monitor for SFTP and it is working when i am executing same from cli. But monitor is failing. Monitor details

!/bin/bash

IP=

echo ${1} | sed 's/::ffff://'

PORT=${2}

sftp -o PubkeyAuthentication=yes -o IdentityFile=/root/.ssh/id_rsa -b /home/sftpmonitor.input -o Port=${PORT} sfglb@{IP} | grep 'test' 2>&1 > /dev/null

mark node UP if expected response was received

if [ $? -eq 0 ] then echo "UP" fi

run util test-monitor ext-sfg-monitor3 address 172.23.176.67 port 20022
