WindowsPath could not be converted to unicode

Question

I have the following python code that is trying to upload a file to a google cloud storage bucket and when i run it i get the following error

 "WindowsPath('sample.flac') could not be converted to unicode"

This my code

from pathlib import Path
from google.cloud import storage

filename = Path(sys.argv[1])
remote_filename = filename.with_suffix('.flac')


def upload_blob(bucket_name, source_file_name, destination_blob_name):
    """Uploads a file to the bucket."""
    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.blob(destination_blob_name)

    blob.upload_from_filename(source_file_name)

    print('  File {} uploaded to {}.'.format(
        source_file_name,
        destination_blob_name))


upload_blob('speech-demo-2',filename,remote_filename)

I can't figure out what is wrong with it. Also my python knowledge is rudimentary at best. I just started learning python a week ago.

EDIT: I am including the full traceback

Traceback (most recent call last):
  File "F:\cloud-speech-to-text\test.py", line 53, in <module>

--UPDATE-- tried snakecharmerb's way and it didn't worked. This is what i get

Answer 1

bucket.blob expects a string as it's blob_name argument, but you are passing it a Path instance - specifically, a WindowsPath.

You can convert the path to string by calling str on it.

>>> p = pathlib.Path('sample')
>>> fn = p.with_suffix('.flac')
>>> fn
WindowsPath('sample.flac') 
>>> str(fn)
'sample.flac'

So this ought to work:

blob = bucket.blob(str(destination_blob_name))
