Unable to identify the reason of the problem

https://github.com/CloudPolis/webdav-client-python/blob/2f011c543264f44d49bea56aebd2815791e7542e/webdav/client.py#L297

I'm unable to understand in my code what was the reason of "missing resouce". For example if it was a 401 Unauthorized error - i will get an exception that webdav.exceptions.RemoteResourceNotFound: Remote resource: /wtf/ not found w/o any reason
