" KeyError: 'targets' " when adding second gateway on ceph-iscsi on ubuntu - BUG

[hamidreza-hosseini]

Hi,
I have installed ceph-iscsi on ubuntu 20 manully (Because I couldn't install via ceph-ansible, I have os compatibility error)
But when I want to add second gateway it will show me error:

OS: Ubuntu 20 LTS
ceph version : octopus
I install cluster with ceph-ansible but I install ceph-iscsi manually via following link:
https://docs.ceph.com/en/latest/rbd/iscsi-target-cli/
(instead of 'yum install ceph-iscsi' I commit 'apt install ceph-iscsi')
gwcli - 2.7

/iscsi-target...-igw/gateways> create ceph-gw-2 192.168.200.30 
Adding gateway, sync'ing 0 disk(s) and 0 client(s)
KeyError: 'targets'

and it will jump out of gwcli!
this is my gwcli log:

What should I do for this problem?
