Init runs in to SlackError 429 (rateLimited)

[kannanmr]

Our workspace is a big one (typical of any medium to large corporate). The initial call to form channel_list is throwing a rateLimited SlackError. I looked through the code for rate_limit_errors handling, dont see any. Is there an option for this, or a fix for this is in the works?

I am running slack-machine==0.32.0

Failed with the latest version as well slack-machine==0.35.0

Hey @kannanmr thanks for the report. I have never encountered this due to using Slack Machine only on smaller workspaces (~150 members). It's good that you brought this to light!

Because I have never encountered this myself (nor have others ever reported this), I'm not working on a fix yet. I can try to figure out a fix, but it will be hard for me to implement a fix, let alone test it, as I do not have access to a workspace where this would happen.

Are you open to try and implement a fix? From what I can see in the documentation, Slack Machine would need to catch the ratelimit (HTTP 429) error and then read the Retry-After header to see how many seconds it has to wait before making a new request.
