New Plugin: Emby.Notification.Slack

[ryderjj89 33]

That would be fine. If you see the URL in my example, if it uses that, that would be fine, at least for me, and probably anyone else that uses something that can preview the images.

[Natilus13 14]

Yeah, a link like that wouldn't be bad. It would also then provide Slack users an easy way to find out more info by clicking on the link.

[ryderjj89 33]

Good morning. Wanted to report that notifications are now broken in Slack. I've updated to 1.2.2 but can't do a test to see if that fixed it. This picture below is in the logs from this morning (before updating to 1.2.2). There was no changelog in either update for slack notifications so I can't tell what was fixed.

I can say that on 1.2.2, I can't do a test because it gives the same 400 bad request error and when I look at the dev tools console, there's the link that runs the test, which when I click on it, I get this: "The file '/emby/Notifications/Services/Test' cound not be found."

[ryderjj89 33]

Giving this a bump @Luke

I see that 1.2.3 came out and I installed that. I see the option to attach the image to the notification so that's great. However, the test is still not working.

I get this in the dev tools console, 500 internal server error with this URL:

https://emby.REDACTED/emby/Notifications/Services/Test?X-Emby-Client=Emby+Web&X-Emby-Device-Name=Microsoft+Edge+Windows&X-Emby-Device-Id=REDACTED&X-Emby-Client-Version=4.8.10.0&X-Emby-Token=REDACTED&X-Emby-Language=en-us&reqformat=json

That link displays just this text:

"The file '/emby/Notifications/Services/Test' cound not be found." Yes, cound is a spelling error here.

Can we get a status update on this? Currently have no working notifications now.

Does unchecking the box to attach images resolve it?

It does not. Doesn't work whether it's checked or not. Just tells me bad request.

[ryderjj89 33]

Good afternoon @Luke

I updated to 4.8.11 today and now there's a new error.

The log is attached.

Here's the main portion.

A 4.8.11 compatibility update is up. Thanks.

Thanks. Just installed 1.2.4 but we are back to the old error message. "Bad Request". This same error happens with and without attaching images.

The plugin has switched to using slack blocks: https://api.slack.com/reference/block-kit/block-elements

Does whatever you're using support that? I'm guessing not.

No. I use Mattermost which for the most part was compatible with slack notifications. Mattermost also supports webhooks, but those don't work from the Webhooks plugin in Emby either.

Slack recommends using block kit now, so that's what we did. A dedicated mattermost plugin would be a better option.

Ah gotcha. I guess Mattermost just hasn't updated to that compatibility, and I don't know if they will. So that's kinda a bummer. I don't have any working notifications now lol. I shot myself in the foot asking for a link to be included. RIP.

Will you guys be able to make a Mattermost plugin? Could that take a while to do?

I've just pushed an update to just the old method as long as you leave the images option unchecked. So you should be fine with that for now.

Yes that works. At least have the bare text notifications back for now. Thanks!

[Natilus13 14]

Does anyone have this working yet? So far, my notifications in Slack have only started using a smaller font. No luck at all with images showing.

Hi there, have you explored the new options in the notification setup screen?

Sorry

I am a bit ocnfused... this entire thread is about these new features not working. I had also provided you log files in this thread, where I originally started having issues with Slack notifications. Cheers 

 

[Luke 42077]

There is a defect in the 4.8.11 server release related to the notification image. It will be resolved in 4.8.12 and is already resolved in the beta channel. Thanks.
