Hello @Arnab Bhowmik ,

It is better to check the Confluence logs that should show the errors on the backend before or while rendering the page for UI so that it is clear what part of app causes the problem. You need to make sure that the plugin web and other resources defined in the manifest are rendered correctly.

[Arnab Bhowmik]

actually in log there is no error is showing which is making it crtitcal to debug 

[Andrii Maliuta]

You can try to use Live Reload of the addon maven tools to debug. You can try to change the settings of the plugin descriptor and see what part (module) is the root cause and then try to debug this very module. SDK gives a lot of tools (also, you can add custom logging with Java code) to check this.
