firebase functions emulators not starting

as you all aware about firebase CLI's new feature which is local emulators explained here(https://firebase.googleblog.com/2020/05/local-firebase-emulator-ui.html?m=1)

so I have updated my CLI and when I run firebase emulators:start I get this error in my functions code

kishan@kishans-Air functions % firebase emulators:start
i  emulators: Starting emulators: functions

⚠  hosting: The hosting emulator is configured but there is no hosting configuration. Have you run firebase init hosting?

   - It appears your code is written in Typescript, which must be compiled before emulation.

can anyone help what I need to do here ??

I found that instead of calling:

admin.initializeApp(functions.config().firebase)

I had to instead call:

admin.initializeApp({
    credential: admin.credential.applicationDefault()
});

This resolved the issue.

The error message is suggesting to you:

It appears your code is written in Typescript, which must be compiled before emulation.

You have to build the code first with npm run build. The emulator will not do that for you.
