I am working with monaco editors 0.27.0 and using for JSON and angular 11. When ever I load editor page I see a strange error

ERROR Error: [createInstance] e depends on UNKNOWN service IMarkerNavigationService.

Can I know what is the issue

@prathyukurra Could you please provide a repro case? Unfortunately I cannot reproduce when running from source, nor when testing with a packaged monaco editor version.

In my env, Angular 12.2.9 and monaco-editor 0.27.0, this issue is seen when the project is built with the production flag and not otherwise.
Let me see, how easy is it to reproduce on a fresh project.

I could reproduce the issue in a fresh angular project.
Here is what I was doing
import 'monaco-editor'

and here is what I did to fix the issue
import { editor } from 'monaco-editor/esm/vs/editor/editor.api';

Hope this helps.

@vimal-m As You mentioned I updated import
From: import * as monacoEditor from 'monaco-editor/esm/vs/editor/editor.api.js';

To : import * as editor from 'monaco-editor/esm/vs/editor/editor.api';

But I still see the same issue
