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]:

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!

You can follow the stack and check where the error takes place. Currently you're the only person who can do that. Consider providing a way to replicate the problem - a plunk, stackblitz, etc. – Jit

Hi, I am interested in this. Did you find any way to fix the issue ? – Vaca

zone's included in most apps in polyfills.ts. polyfills.ts is included by angular.json. Have you modified either of these files? – Fingerling

has anyone solved this yet? I'm encountering the exact same error. – Despondent

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.
