Ionic 7, Capacitor, Error saving image to Firebase Storage

I am trying to save a picture to Firebase storage using the Capacitor Camera plugin.

It works fine when the picture is taken from the web browser. However, when taking a picture on an android phone, the following errors occur…

FirebaseError: Firebase Storage: An unknown error occurred, please check the error payload for server response. (storage/unknown)

the error from CapacitorHttp.request

    "headers": {
        "Access-Control-Allow-Origin": "*",

    "data": "Multipart body does not contain 2 or 3 parts.",
    "error": true
}

So it appears “Multipart body does not contain 2 or 3 parts” causes and issue from android.

The code is as follows

  public async addNewToGallery(photoPathId: string) {
    // Take a photo
    const image: Photo = await Camera.getPhoto({
      quality: 90,
      allowEditing: false,
      resultType: CameraResultType.DataUrl,
    });
    await this.uploadImage(image, photoPathId);
  }

  async uploadImage(cameraFile: Photo, photoPathId: string) {

    const path = `uploads/${photoPathId}/${new Date().getTime()}.png`;
    const storageRef = ref(this.storage, path);

    try {
      // this Firestore method is not working
      await uploadString(storageRef, cameraFile.dataUrl!, 'data_url')
      const imageUrl = await getDownloadURL(storageRef);
      this.updateUserPhotos(imageUrl, photoPathId, path);
      return true;
    } catch (e) {
      console.log('error from upload?', e);
      return null;
    }
  }

Any ideas to solve this would be very helpful
