NativeScript Android app closes when trying to add a marker in Google Maps

I'm having a problem with my code. I'm just trying to add a simple marker. Here's my implementation

<script setup lang="ts">
import { AbsoluteLayout, Page } from '@nativescript/core';
import type { GoogleMap } from '@nativescript/google-maps';
import { ref } from 'nativescript-vue';

const mapRef = ref<GoogleMap | null>(null);

const handleMapReady = (args: { map: GoogleMap }) => {
  console.log("Map is ready");
  mapRef.value = args.map;

  mapRef.value.addMarker({
    position: {
      lat: 1.4478297,
      lng: 124.8293001,
    }
  });
};
</script>

<template>
  <Page>
    <AbsoluteLayout width="100%" height="100%">
      <MapView
        width="100%"
        height="100%"
        @ready="handleMapReady"
      />
    </AbsoluteLayout>
  </Page>
</template>

But the app keeps closing. No force close message. No error in console. The last log entry is just:

Map is ready

Remove the .addMarker() statement, and the app runs just fine.

Here's the versions of NS core and the Google Maps plugin:

{
  "@nativescript/google-maps": "^1.8.0",
  "@nativescript/core": "~8.9.1"
}

Also, app.ts in case it matters:

import { createApp } from 'nativescript-vue';
import GoogleMaps from '@nativescript/google-maps/vue'
import App from './App.vue';

createApp(App)
  .use(GoogleMaps)
  .start();
