Uploading zip file through file loader

[ayeshazahid913]

What I’m trying to do:
is to upload a zip file using file loader but getting this error

Here is my python code:

from zipfile import ZipFile
import anvil.media

@anvil.server.callable
def unzip(a):
     with ZipFile(a, 'r') as zip:
        zip.extractall()
