stone_validators.ValidationError

jyotinarang You're getting a slightly different error than what was originally reported on this thread, so you're likely hitting a different issue.

It sounds like you're providing a string to the 'shared_link' arg, instead of a SharedLink instance. That is, instead of doing something like this:

shared_link_url = "..."
res = dbx.files_list_folder(path="", shared_link=shared_link_url)

You need to do something like this:

shared_link_url = "..."
res = dbx.files_list_folder(path="", shared_link=dropbox.files.SharedLink(url=shared_link_url))

If that doesn't seem to be the problem, please open a new thread with the details, e.g., the code you're using to reproduce the issue, and we'll take a look.
