Patron,Etcd and Confd

Hello

I am using ETCD as DCS for Patroni. (3.5.0 latest version) My Postgres
version is 13. Postgres and Patroni cluster are running. I can see the
leader and replicas. Data is synchronized. Patroni and Etcd have no
problem running Postgres. I am able to read key variables using
etcdctl. It just can't read Confd. The problem seems to be confd. I am
getting an error as below.

-% Versions:
Etcd version: 3.5.0
Confd version: 0.11.0
Postgres 13.4

What could be causing the problem? Has anyone used it before?

Thanks.
