Fails to delete any files

[kellyschoenhofenfpx]

I orginally tried to delete all files for everyone older than July 1st, e.g.:
slack-cleaner --token xxx --file --user "*" --before 20170701
It says 391 will be deleted, try again with --perform. I do it again:
slack-cleaner --token xxx --file --user "*" --before 20170701 --perform
and it errors on all 391 it looks like, with the following for each:
Failed to delete (delete() got an unexpected keyword argument 'as_user') ->

I restricted it to myself:
slack-cleaner --token xxx --file --user "kelly" --perform
which should have deleted a handful of files and I get the same error.
Running slack-cleaner v0.4.0
Deleting all matching files
Failed to delete (delete() got an unexpected keyword argument 'as_user') ->
(etc)

Ideas?

PS I did try with --rate=5 just to make sure throttling wasn't an issue and it's the same error.
