I’ve configured a few channels to post to slack in the discourse-chat-integration configuration. One of the channels is being posted to via the Discourse API and under certain circumstances those posts end up in Discourse but not in Slack. Using the test harness with those unsuccessful topics results in a 500 with a null in the error detail:
but logs this:
URI::InvalidURIError (can not set host with registry or opaque) /usr/local/lib/ruby/2.5.0/uri/generic.rb:594:in

with a stack trace like

Our subsequent testing seems to indicate that full email addresses seem to trip up the Slack posting; content that looks like this seems to work:

but content like this:

does not.
The Slack posting failure happens whether the topics with suspect content are created via the API or in the UI.
We want full email addresses to post to these topics (they’re being created in a staff-only category and we need the contact information and many of those users will not be forum members); any ideas how we can get those to come through successfully?
