Raj,

Are you using localhost or file in the url? If so that is the issue i 4.8 you have to use your machine name in the url when developing

What is the url that you are using to develop your app?

Raj,

No, not the url of a service you are using but the url that you have in your browser to run your app.

OK, but you understanding my question about the url you are using when accessing your developed application likely has a large impact on that error. So when I am developing on my laptop I have my html files in a certain directory (say c:/JSWorkspace) and that folder in setup as a virtual folder in IIS so that I can access it using a url like http://gislap183/js/ in my web browser. So if I am working on testing.html then the url I use to debug and run my app is http://gislap183/js/testing.html. Now if you are using file:///C:JSWorkspace/testing.html in your browsers url then that is what I mean by file system url. If you are using http://localhost/js/testing.html that that is what I mean by localhost. Neither of those urls will working in JS API 4.8 properly.

RAJ,

I have no experience using Web Server for Chrome extension. But it is likely running into the same issue that 4.8 does when you use localhost or file based urls. Does your machine not have IIS installed?

No, don't have IIS... can you tell me one thing. even the feature layer is not working with 4.8... only working with 4.7 JS...

Is there any possiblity to use the same url with 4.8..

Or need to update service itself..

It has nothing to do with the service it has to do with a change that was made in the 4.8 API which no longer allows localhost or file system urls to work without error.

RAJ,

There is nothing you can change in your code to make it work either. The issue is the development environment. Starting in 4.8 API a loopback url like 127.0.0.1 also known as localhost is considered a secured source and will use https protocol by default. So if your web server or your case the web server extension is not setup for https you will get an error like you are seeing because a service url is using a different protocol and thus the ERR_CERT_AUTHORITY_INVALID error.

Your fix to this would be quit using Chrome Web Server extension and start using your machines IIS and the machine name in the url. Then you will not have any issue.
