channels.list deprecated

[pwoolvett]

Today slack-cli stopped working

https://api.slack.com/changelog/2020-01-deprecating-antecedents-to-the-conversations-api

We'll stop allowing newly created Slack apps to use these deprecated APIs beginning June 10th, 2020.

:(

related: https://github.com/os/slacker/issues/116

temporary workaround (I dunno about side effects, Im only using it to PM me):

1. upgrade slacker: pip install --upgrade slacker
2. change the channel fetcher in slackcli.messaging:iter_resources to lambda: slack.client().conversations.list().body["channels"]
3. comment out the group fetcher

EDIT: This no longer works as pkg_resources avoids newer slacker versions, as reported by @william-dowling

It stopped for me too:

Trying @pwoolvett solution today (17 Sept 2020) gets this for me:

Trying again, this time remembering to run pip install --upgrade slacker

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

slack-cli 2.2.9 requires slacker<0.12.0, but you'll have slacker 0.14.0 which is incompatible.

I use slack cli for deleting bot created channels like this: https://blog.rmotr.com/how-to-delete-multiple-slack-channels-at-once-7ba00f4890cd

and replacing line 80 of api.py with resp = self.__request('conversations.list', **kwargs)

got me taken care of
