Код загрузки веб-файла Firebase: "app / duplicate-app"

Я пытаюсь загрузить изображения и видео через firebase на свой сайт, первая загрузка работает, вторая загрузка показывает это сообщение на моей консоли:

firebase.js:1 Uncaught {code: "app/duplicate-app", message: "Firebase: Firebase App named '[DEFAULT]' already exists (app/duplicate-app).", name: "[DEFAULT]", stack: "[DEFAULT]: Firebase: Firebase App named '[DEFAULT]…(https://code.jquery.com/jquery-3.3.1.js:4991:28)"} code: "app/duplicate-app" message: "Firebase: Firebase App named '[DEFAULT]' already exists (app/duplicate-app)." name: "[DEFAULT]" stack: "[DEFAULT]: Firebase: Firebase App named '[DEFAULT]' already exists (app/duplicate-app).↵ at error (https://www.gstatic.com/firebasejs/5.5.3/firebase.js:1:49452)↵ at Object.initializeApp (https://www.gstatic.com/firebasejs/5.5.3/firebase.js:1:48095)↵ at fileInput (http://xxx.tv/theme/js/js.js:115:12)↵ at HTMLAnchorElement.

Также, когда я пытаюсь загрузить видео, он не работает, он возвращает сообщение, что я не отправляю никаких данных:

Uncaught e {code_: "storage/invalid-argument", message_: "Firebase Storage: Invalid argument in put at index 0: Expected Blob or File.", serverResponse_: null, name_: "FirebaseError"}

HTML:

    <label for = "videoUpload">
        <i for = "videoUpload" class = "material-icons videoUploadIcon">videocam</i>
        <input id = "videoUpload" class = "videoUpload" type = "file" accept = "video/*" style = "display: none;">
