PostgreSQL/PostDock: Auto recovery failed in master node

I run:
docker network create -d overlay postdock
docker stack deploy -c docker-compose.yml postdock
and things work smoothly.
However, after I update the services multiple times, then the auto failover on master node failed. In the master node log file, I noticed that the recovery process cannot detect the database replication_db and the schema replication_db.public:
>>> Waiting for local postgres server start...,
expr: non-integer argument,
>>> Wait schema . on pgmaster:5432(user: public,password: *******), will try times with delay 10 seconds (TIMEOUT=)
As you can see, there is no schema specified, only the dot sign ".", and the user is also wrong: It should be replication_user, not the user public
which leads to this error message:
2018-11-16 04:45:33.310 UTC [122] FATAL: password authentication failed for user "public",
2018-11-16 04:45:33.310 UTC [122] DETAIL: Role "public" does not exist.,

>>>>>> Host pgmaster:5432 is not accessible (will try times more),
expr: non-integer argument,
As I understand, when the auto failover succeeds, the expected recovery log should be:
>>> Waiting for local postgres server start...,
>>> Wait schema replication_db.public on pgmaster:5432(user: replication_user,password: *******), will try 9 times with delay 10 seconds (TIMEOUT=90),
>>>>>> Schema replication_db.public exists on host pgmaster:5432!,
>>> Registering node with role master
Anybody have any idea about the root cause of this issue ?
