`not_authed` error with Slack integration

[shifuma]

Describe the bug

I have a Slack integration setup and connecting properly, however, when I trigger a submission to post to Slack I get this error: API error: “not_authed” /home/mysite.com-deploy/mysite.com/18062024_025339/vendor/verbb/auth/src/clients/slack/provider/exception/SlackProviderException.php:19

I've double and triple-checked my Client ID & Secret and they're correct. When deliberately using the wrong secret and trying to connect the integration, I get a different error. So I'm confident those are right.

On the Slack side, I've setup the Redirect URL and authorised the app properly. The only Scope under OAuth & Permissions is incoming-webhook, but that's been the same since Craft 4.

Have I missed anything in the setup?

Additional context

I recently upgraded to Craft 5 / Formie 3. Prior to that this was working ok.

Can I ask what sort of "Channel Type" you're using? Is it a channel, direct message or webhook?

[shifuma]

I was using a Public Channel previously. Now I'm not able to select it - I get the same not_authed error when refreshing the channels. The same happens with Direct Message selected (the error is not showing in the browser, but is in the logs)

Looks like this was an issue with the auth module. You should be able to get that updated alongside Formie via composer require verbb/formie:"dev-craft-5 as 3.0.0-beta.15" -W.

Thanks Josh! That resolved it for me.
