Cordova camera plugin not launching camera

cordova
1

I’m using Ionic4 on Angular with Capacitor and the Cordova Camera Plugin. I installed the plugin as instructed on the Capacitor docs:

npm install cordova-plugin-name
npx cap sync

Everything builds fine, it’s only when I try to invoke the getPicture method that I get an issue.

Here’s the relevant code from my component:

Import

import { Camera, CameraOptions } from '@ionic-native/camera/ngx';

Within my component class:

cameraOptions: CameraOptions = {
  destinationType: this.camera.DestinationType.FILE_URI,
  mediaType: this.camera.MediaType.VIDEO,
};

onPickVideo() {
  if (this.platform.is('cordova')) {
    this.camera
      .getPicture(this.cameraOptions)
      .then(videoData => {
        console.log(videoData);
      })
      .catch(err => {
        this.filePickerRef.nativeElement.click();
        console.log(err);
      });
  } else {
    this.filePickerRef.nativeElement.click();
  }
}

I can provide the Ionic project config.xml on request.

I run a development server using ionic capacitor run android -l --external --consolelogs

When I press the button that invokes onPickVideo() I get the following output in Android Studio’s Logcat at Warn level:
