Hi Sujeet,
The provided info is limited but from what I can see on the screenshot the URL in the address bar does not seem correct.
If I understand correctly you are building a remote plugin and trying to navigate to a custom object defined by the plugin. This is a very wild guess based on the URL but if it is the case - custom objects are not supported by remote plugins. Hence, you can't navigate this way.
If what you are trying to achieve is deep linking you need to provide the special details in the options of the navigateTo API.
All this is very vague based on the screenshot so please provide more info of what you want to implement and what steps you do to reach this result.
Thanks and cheers,
Vladi
