dbx.files_list_folder_continue(curson) fails when using SharedLink

Hi, 

I am listing a password-protected folder shared via a link. 

result = dbx.files_list_folder(path=root, shared_link=dropbox.files.SharedLink(url=url, password=password))
for entry in result.entries:
    if isinstance(entry, dropbox.files.FolderMetadata):
        # do some action with a folder
    else:
        # do some action with a file

while result.has_more:
    result = dbx.files_list_folder_continue(result.cursor)
    for entry in result.entries:
        if isinstance(entry, dropbox.files.FolderMetadata):
            # do another action with a folder
        else:
            # do another action with a file

dbx.files_list_folder() call goes through all right, however dbx.files_list_folder_continue(result.cursor) fails everytime and the message is not very explanatory:

dropbox.exceptions.ApiError: ApiError('5c91fda84dd6487b9357c3a72be962e7', ListFolderContinueError('path', LookupError('not_found', None)))

Any guesses what is wrong? Cheers.
