ios – How to upload specific documents to firestore

I am trying to upload my imageUrl to firestore but its being uploaded to firebase with a extra field videoUrl being attached to it but I am only uploading a image and within my imageUploader only a Uiimage is classified not a video so why is my imageUrl post being uploaded with a extra field as the videoUrl and I didn’t upload a video with the image post nor is it written that way in my code. What is wrong with my code and how do I rewrite this code to upload my image to firestore without the videoUrl field

class UploadPostViewModel: NSObject, ObservableObject {

  @Published var didUploadPost = false
  @Published var isLoading = false
  @Published var error: Error?
  @Published var videos = [Video]()
  @Published var mediaPreview: Movie?
  @Published var profileImage: Image?
  @Published var text = ""
  @Published var selectedImage: PhotosPickerItem? {
    didSet {
      Task { await loadImage(fromItem: selectedImage) }
      Task { try await uploadVideo() }
    }

  }
  private var uiImage: UIImage?

  func uploadPost(caption: String) async throws {
    guard let uid = Auth.auth().currentUser?.uid else { return }

    var videoUrl: String? = nil
    let items = selectedImage
    if let videoData = try await items?.loadTransferable(type: Data.self) {
      videoUrl = (try await VideoUploader.uploadVideo(withData: videoData))!
    }
    var imageUrl: String? = nil
    if let image = uiImage {
      imageUrl = try await ImageUploader.uploadImage(image: image, type: .post)

      let post = Post(
        ownerUid: uid,
        text: text,
        videoUrl: videoUrl, likes: 0,
        replyCount: 23,
        imageUrl: imageUrl, timestamp: Timestamp()
      )

      try await PostService.uploadPost(post)
      self.didUploadPost = true

    }

  }

  func loadImage(fromItem item: PhotosPickerItem?) async {
    guard let item = item else { return }

    guard let data = try? await item.loadTransferable(type: Data.self) else { return }
    guard let uiImage = UIImage(data: data) else { return }
    self.uiImage = uiImage
    self.profileImage = Image(uiImage: uiImage)
  }
  func uploadVideo() async throws {

    guard let items = selectedImage else { return }
    guard let videoData = try await items.loadTransferable(type: Data.self) else { return }
    guard let videoUrl = try await VideoUploader.uploadVideo(withData: videoData) else { return }
    try await Firestore.firestore().collection("videos").document().setData(["videoUrl": videoUrl])
  }
}
