slacker.Error: missing_scope
Get this error running:
slack-cleaner --token <TOKEN> --file --user "*"
Using the slack-cleaner installed from pip.
Tried adding all scopes to my app and reinstalling app.
Same here. Probably a change in the slack API. I'm currently having a look. Will share any fixes I can find
I got it working (partially) by generating a token here. I believe slack switched to integrated apps, which probably handles requests differently.
Also, I said partially working, since this token is bound to a user, meaning you can only clear messages for the user to which the token belongs.
The "legacy tokens" are no longer available, so you need a user_scope with one of the sets of permissions listed at https://github.com/sgratzl/slack-cleaner.
