Error No provider for NgZone

Question

I have an application that uses Angular Google Maps to show a location. At the beginning I was able to show the map, but since a while (probably I have modified something) I am getting the following error:

ERROR Error: Uncaught (in promise): Error: StaticInjectorError[NgZone]: 
StaticInjectorError[NgZone]: 
NullInjectorError: No provider for NgZone!

My code is: app.module.ts:

import { AgmCoreModule } from '@agm/core';

imports AgmCoreModule.forRoot({apiKey:'...'})

mycomponent.html

<agm-map [latitude]="lat" [longitude]="lng" [zoom]="zoom">
    <agm-marker [latitude]="lat" [longitude]="lng">
        <agm-info-window>
            <div>
                my text
            </div>
        </agm-info-window>
    </agm-marker>

I would really appreciate your help!

Answer 1

You can provide NgZone manually:

import { NgZone } from '@angular/core';

@NgModule({
    providers: [
        // ...
        { provide: NgZone, useFactory: () => new NgZone({}) }
    ]
})

Answer 2

You need to add peerDependencies with all the libraries you are using using.

Also check by removing each Module from your imports to see which one is causing the issue. This link should help.
