Failed to delete (cant_delete_message)-> about slack-cleaner HOT 13 CLOSED

does it return the cannot delete message error message or are just no messages are about to be deleted. In the latter case, could be a duplicate to #38

from slack-cleaner.

Having the same issues. I have a channel with lot's of messages from an app bot I have. When I di

slack-cleaner --token ${TOKEN} --message --channel ${CHANNEL} --bot --perform --rate 2

I get Failed to delete (cant_delete_message)->. Any idea how to solve this and way I get this?

I can delete users messages ok, but issues are with bot ones.

Thx.

Hi can you try the develop branch of this project. it follows a different approach, a pure python one. but allows you more control about which messages should be deleted.

https://github.com/sgratzl/slack-cleaner/tree/develop and https://slack-cleaner2.readthedocs.io/en/latest/modules.html

thus it would be easier to come up with a more specific reason why the message cannot be deleted

from slack-cleaner.

I did and I get

When running:

slack-cleaner --token ${TOKEN} --message --channel ${CHANNEL} --bot --perform --rate 2

Hi @sgratzl, any update on this issue?

from slack-cleaner.

the easiest way would be to write a custom python script and use the library directly.

e.g. untested python code but should be quite right

from slack_cleaner2 import *

s = SlackCleaner(TOKEN, sleep_for=2)
channel = next((c for c in s.channels if c.name == CHANNEL), None)
if channel:
  for msg in channel.msgs():
    if msg.bot:
      msg.delete()

from slack-cleaner.

re cli: you can try to add --user "*"

from slack-cleaner.

@sgratzl still getting the same issues with cant_delete_message with the code you're mentioning.

How can we know that is the issues? I'm using a legacy token.

from slack-cleaner.

when looking at https://api.slack.com/methods/chat.delete there are the following restrictions:

When used with a typical user token, may only delete messages posted by that user.

When used with an admin user's user token, may delete most messages posted in a workspace.

When used with a bot user's token, may delete only messages posted by that bot user.

so are you an admin? Moreover, you can try to set the as_user flag as in

msg.delete(as_user=True)

from slack-cleaner.

Hi.

Sorry, I was not admin, with admin token I can delete now.

Thx!

from slack-cleaner.

happy that you found the issue

from slack-cleaner.

from slack_cleaner2 import *

s = SlackCleaner(TOKEN, sleep_for=2)
channel = next(c for c in s.channels if c.name == CHANNEL, None)
if channel:
  for msg in channel.msgs():
    if msg.bot:
      msg.delete()

little syntax change, channel = next((c for c in s.channels if c.name == 'random'), None)
missing paranthesis
