Not stale. Still waiting for an answer :)

Your redirect uri needs to be /auth/name_of_provider/callback

So #{ENV['BASE_URL']}/auth/sign_in_slack/callback

Don't have capacity to try this again right now but i'll let you know when i do

I am not sure but, try removing the redirect_uri param and let the gem generate one automatically .
maybe the endpoint that should trigger the callback_phase is not being called because of that.

@kwent did this resolve your problem?

Is this a requirement ? We have this in our routes.rb so shouldn't matter

get "/auth/slack/callback/sign_in" => "omniauth_callbacks#sign_in_slack"

from omniauth_openid_connect.

I had the same issue and apparently it is a requirement:

When I had my redirect URL set to just /auth/slack/callback, I also got request.env['omniauth.auth'] nil.
But changing it to /auth/slack/callback (where name: :slack in the OmniAuth::Builder config) I get a CSRF error from the callback phase (which is at least progress).

(Ok for reference, my CSRF issue was dumb: I have ngrok pointing at localhost:3000, but I was starting the authorization from localhost:3000, so the "omniauth.state" cookie (which is used for CSRF protection) was set on localhost and so wasn't available in the callback phase, since that used the ngrok url)

This didn't work for me: this gem doesn't seem to try to construct a redirect_uri? I had a look at the dependent gems as well and they don't seem to either.

Here's the result from Slack of passing it as nil:

I eventually got this working by overwriting the redirect_url method to match what Slack wanted: https://github.com/sunchaserio/omniauth-sign-in-with-slack/blob/main/lib/omniauth/strategies/slack.rb
