AEM SPA Error Page Handler

[Leela-Pavan-Kumar]

I have followed the AEM SPA Editor Error Page Example | AEM Community Blog Seeding for 404 Error Pages thorugh ACS Common Error Handler.

It is working absolutely fine but whenever we add a selector to the wrong path, 404 Error Page content is not rendering but the model.json is loading in Network. 

In the above image with "/home1" the error page loading but with "/home1.abc" it is not loading.

How to resolve this issue?
