I've linked Slack and our Jira Cloud instance, and "/jira connect" let me attach a Jira project to a public channel.
However, when I do "/jira manage", I run into problems. The command provides a "Manage subscription" link. I click on that, and get a page with 4 error messages:
-----

It looks like this all starts when the following REST API call fails with a 500 error:
https://jira-slack-integration.prod.atl-paas.net/api/channels/XXXXXXXX
(I've obscured my channel ID on the previous line.)
