I have this command

%%bash -s “$FABRIC_SLICE_PRIVATE_KEY_FILE” “$FABRIC_BASTION_USERNAME” “$FABRIC_BASTION_HOST” “$ROUTER1_USER” “$ROUTER1_IP” “$router1Cmd”
ssh -q -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i $1 -J $2@$3 $4@$5 << EOF
##############################################

cd
echo “hello” > hello.txt
##############################################
exit
EOF

 

 

getting the following error, any comments on how to fix the issue or what the issue is?

Host key verification failed.
