Hey Husky,

You can provide just the path to the file to upload with REST Api call. https://docs.databricks.com/api/workspace/files/upload. Its in Public Preview. Please see below.

def return_ws_url():
    workspace_url = dbutils.notebook.entry_point.getDbutils().notebook().getContext().tags().get("browserHostName")
    match = re.match(r'Some\((.*)\)', str(workspace_url))
    if match:
      value = match.group(1)
      return(value)
    else:
        print("No value found")

def upload_ws_file_to_volume(local_path, remote_path):
  with open(local_path, 'rb') as f:
    r = requests.put(
      'https://{databricks_instance}/api/2.0/fs/files{path}'.format(
        databricks_instance=return_ws_url(), path=remote_path),
      headers=headers,
      data=f)
    r.raise_for_status()

headers = {'Authorization' : 'Bearer {}'.format(dbutils.notebook.entry_point.getDbutils().notebook().getContext().apiToken().get())}
print(headers)
