Dear support,

Also please guide me on how to uninstall this custom icon later when I want to remove/disable it.

Have you had a look at the docs for adding a cPanel plugin?
Guide to cPanel Plugins - Software Development Kit - cPanel Documentation

 

[Sanson]

Yes I did follow
Tutorial - Add a Link to the cPanel Interface - Software Development Kit - cPanel Documentation
and
Guide to cPanel Plugins - Add Plugins to Version 11.44 and Later - Software Development Kit - cPanel Documentation

and created dockericons.tar.gz as per the docs. Please refer the attachment file.zip (.tar.gz attachments are not supported).
Then when I run the command

/usr/local/cpanel/scripts/install_plugin dockericons.tar.gz --theme paper_lantern

 

[Infopro]

Zip file removed, no need for that here. You might want to re-check your code.

The system failed to parse the JSON stream data

There are several other threads on the forum with this error easily found via google, here's one:
The system failed to parse the JSON stream data

You should have a peek at those for hints to the issue your having.

 

[Sanson]

I searched the web but all problems are related to JSON when creating email/sub-domain/webmail
But I have no problems on all that.

I think there is a problem only in the install_plugin script on my cPanel Instillation.

This was my orginal code because it gave error I decided to just try with one icon and that too failed.

       "order" : 1,
       "name" : "Docker",
       "type" : "group",
       "id" : "my_docker"
    },
    {
       "icon" : "container.svg",
       "group_id" : "my_docker",
       "order" : 1,
