Slack /discourse post command hug on `loading transcript`


We’re trialing Discourse for our team and I’m running into an issue.

When trying to use the /discourse post thread xxxxxxx command within Slack, I get a message saying “loading transcript”, but nothing else.

In the logs in the admin panel, I see this:

/var/www/discourse/plugins/discourse-chat-integration/lib/discourse_chat/provider/slack/slack_command_controller.rb:85:in `block in process_post_request'

/var/www/discourse/lib/scheduler/defer.rb:94:in `block in do_work'

rails_multisite-2.5.0/lib/rails_multisite/connection_management.rb:294:in `with_connection'
rails_multisite-2.5.0/lib/rails_multisite/connection_management.rb:73:in `with_connection'
/var/www/discourse/lib/scheduler/defer.rb:89:in `do_work'

/var/www/discourse/lib/scheduler/defer.rb:79:in `block (2 levels) in start_thread'

I saw a similar post that had issues with the app not being added to the channel, but that’s not the case here. The app is able to post when someone starts a thread in Discourse, for example.

Thanks for any help!
