Nifi CLI toolkit errors

[#1]

Hello Supporters,

I am trying to use NIFI CLI toolkit so that I can load 100 parameters using parameter context. (doing it using UI is a tedious job and not appropriate for deployments as well) 

I installed Nifi toolkit on remote server. I generally ssh into this server from local and run my commands.

To see the UI, I use ssh tunnel.

There is only one user for this Nifi Instance (admin) and it don't have https certificates. (Single User Authentication)

When i start CLI prompt it works fine (below)

# sh cli.sh
CLI v1.16.3

Type 'help' to see a list of available commands, use tab to auto-complete.

Session loaded from /root/.nifi-cli.config

#>

But when I use any Nifi commands, it throws below error:

#> nifi list-param-contexts -u http://localhost:8443/

ERROR: Error executing command 'list-param-contexts' : Unexpected end of file from server

if I use https , 

#> nifi list-param-contexts -u https://localhost:8443/

ERROR: Error executing command 'list-param-contexts' : truststore, truststoreType, and truststorePasswd are required when using an https url

But I don't use truststore or passwords for single admin user.

Also commands related to Registry working fine.

#> registry current-user -u http://localhost:18080
anonymous

#> registry list-buckets -u http://localhost:18080

# Name Id Description

2 delete 4df052fd-fddc-4e7b-b4ea-bb3b8b691385

Is this something related to https/URI  ?

I don't find much information online for this issue and I was struck from many days..

Please help me solve this.

I am using CLI version 1.16.3

So, I was thinking in this direction that this CLI supports only HTTPS connections.

and I must use truststore and without it there is no way..

(But I don't want to complicate things by using truststore etc. as the remote server can only be accessed by secure ssh.)

Please let me know if i am thinking in right direction...

Update:

So i copied the details of nifi.security.keystore

nifi.security.truststore

nifi.security.truststorePasswd

nifi.security.truststoreType 

from nifi.properties file of my nifi installation and pasted them in the properties file of toolkit

nifi-toolkit-1.16.3/conf/cli.properties

Now when i try to run the cli commands i get a new error.. seems I am close but not yet done...

below is the error:

"ERROR: Error executing command 'list-param-contexts' : Error retrieving parameter contexts: Client certificate for (CN=localhost) is expired."

How can I renew this expired certificate ?  I wonder why CLI is not so straight forward!!!

Please help me in this regards..
