Running into "Cannot read properties of null (reading 'appendChild')"

[hangrydave]

Describe the bug I've got an Ionic project using this plugin, and when I call CameraPreview.start this error gets spit out in the console:

core.mjs:9215 ERROR Error: Uncaught (in promise): TypeError: Cannot read properties of null (reading 'appendChild')

To Reproduce Version numbers that are probably relevant:

• Ionic CLI 6.20.4
• Node 18.12.1
• Capacitor Android 4.6.0
• Capacitor Camera 4.1.4
• Capacitor CLI 4.6.0
• Capacitor Core 4.6.0

I'm running this code:

const cameraPreviewOptions: CameraPreviewOptions = {
      position: 'rear',
      height: 1920,
      width: 1080
    };
CameraPreview.start(cameraPreviewOptions);

The error occurs whenever that code is run. Issue #247 looked similar, but the fixes linked here didn't work for me: https://github.com/Cap-go/camera-preview/pull/3

Any help is appreciated, thanks.
