Some content does not post to Slack via the chat integration

cori · January 2, 2019, 8:31pm

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:incheck_host’`

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:

* Project Name: https://glitch.com/~test-project,
* Project Id: 2bdfb3f8-05ef-4035-a06e-2043962a3a13,
* Submitted by: anonymous
* Contact: cori@glitch
* Message: This

but content like this:

* Project Name: https://glitch.com/~test-project,
* Project Id: 2bdfb3f8-05ef-4035-a06e-2043962a3a13,
* Submitted by: anonymous
* Contact: cori@glitch.com
* Message: 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?

Any ideas here @david?

david · January 2, 2019, 9:46pm

It does look like a bug in the plugin - I’ll take a look tomorrow.

david · January 3, 2019, 11:19am

Thanks for the detailed report @cori, this is now fixed. I’ll try and get it deployed to your site later today.

That’s perfect, @david, thanks! We just deployed the feature that relies on this so this timing is great. Thanks for the quick fix!

2 posts were split to a new message: Support.glitch.com background processes

Ok now that some other issues have been resolve it does still seem like we’re not quite all the way there on this fix, at least for our usage.

I used our newly-deployed API-based posting mechanism, and am seeing the topic created in our forum but it doesn’t make it to slack. A reply to that topic does make it to slack, but a subsequent reply with an email address still does not.

Here’s what our forum looks like, about 15 mins after the last reply:

Here’s Slack at the same time:

So as you can see the initial post and the 2nd reply didn’t make it into Slack, but the first reply (without an email address) made it in right away. I don’t see anything relevant in the logs, and the chat integration test harness seems to work consistently.

david · January 3, 2019, 7:29pm

Ah… my apologies. I jumped the gun a little when I deployed your site earlier, and the fix hadn’t quite made it through our CI pipeline. I’ve just deployed your site again, so can you please give it another try?

On my test site, I’m now able to send messages with mailto links:

cori · January 3, 2019, 7:37pm

Awesome thanks it appears to be working! Thanks for your help!
