Incorrect return type of Response on upload method from supabase.storage.from_

[RafayAK]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

The upload method coming supabase.storage.from_ has the return type of Response in the storage3/_sync/file_api.py:

# excerpt from file_api.py

    def upload(
        self,
        path: str,
        file: Union[BufferedReader, bytes, FileIO, str, Path],
        file_options: Optional[FileOptions] = None,
    ) -> Response:  <<<<<<<<<<< THIS
        """
        Uploads a file to an existing bucket.

        Parameters
        ----------
        path
            The relative file path including the bucket ID. Should be of the format `bucket/folder/subfolder/filename.png`.
            The bucket must already exist before attempting to upload.
        file
            The File object to be stored in the bucket. or a async generator of chunks
        file_options
            HTTP headers.
        """
        return self._upload_or_update("POST", path, file, file_options)

While the method _upload_or_update returns an UploadResponse type object :

# excerpt from file_api.py

    def _upload_or_update(
        self,
        method: Literal["POST", "PUT"],
        path: str,
        file: Union[BufferedReader, bytes, FileIO, str, Path],
        file_options: Optional[FileOptions] = None,
    ) -> UploadResponse:  <<<<<<<< THIS
        """
        Uploads a file to an existing bucket.

        Parameters
        ----------
        path
            The relative file path including the bucket ID. Should be of the format `bucket/folder/subfolder/filename.png`.
            The bucket must already exist before attempting to upload.
        file
            The File object to be stored in the bucket. or a async generator of chunks
        file_options
            HTTP headers.
        """

To Reproduce

This inconsistency breaks some of the code in tutorials where for example a 200 response is being checked on a Response type object here . For example:

from supabase import create_client, Client

SUPABASE_URL = os.getenv('SUPABASE_URL')
SUPABASE_KEY = os.getenv('SUPABASE_KEY')
SUPABASE_BUCKET = os.getenv('SUPABASE_BUCKET')


# Initialize Supabase client
supabase: Client = create_client(SUPABASE_URL, SUPABASE_KEY)

res = supabase.storage.from_(SUPABASE_BUCKET).upload(image_filename, file_content)
if res.status_code == 200:   # <<<<<<<< THIS WILL THROW AN ERROR `AttributeError: 'UploadResponse' object has no attribute 'status_code'`

    print("success!")

Expected behavior

The correct HTTP Response type should be returned with the relevant attributes.

Screenshots

I can provide a screenshot but I think I've debugged where the error is coming from.
