Driver [slack] not supported.

[rjchauhan]

• Slack Notification Channel Version: 2.0.0
• Laravel Version: 5.8.9
• PHP Version: 7.2.8
• Database Driver & Version: MySql

Description:

I've upgraded Laravel version from 5.7 to 5.8 and installed slack notification channel package via composer. But somehow slack notifications stopped working. composer dumpautoload discovers this package but seems like it's not registering slack notification channel.

I've traced the code with xdebug and found that createSlackDriver() method is not found on laravel/framework/src/Illuminate/Support/Manager.php:95. Due to this "Driver [slack] not supported" exception occurs.

[driesvints]

This shouldn't be necessary anymore since the service provider now registers the slack channel: https://github.com/laravel/slack-notification-channel/blob/2.0/src/SlackChannelServiceProvider.php

[rjchauhan]

Yes, It just works fine and registers slack channel auto if I setup fresh Laravel 5.8. But the above issue occurs on my older projects where I upgrade Laravel from 5.7 to 5.8.

[yehudahkay]

I have the same issue on a fresh installation

[yehudahkay]

I ran composer require on local and then pushed those changes. I found that running it on the server fixed the issue. Here is the diff after running on the server.

Yes, It just works fine and registers slack channel auto if I setup fresh Laravel 5.8. But the above issue occurs on my older projects where I upgrade Laravel from 5.7 to 5.8.

@rjchauhan then there's something that's not updated to the project when upgrading. We need to figure out what. Have you followed every step in the upgrade guides?

https://laravel.com/docs/5.7/upgrade https://laravel.com/docs/5.8/upgrade

@yehudahkay that diff doesn't seems to be related to this issue but a file permissions thing?

[yehudahkay]

It wasn't working with push from local. I then tried require on the server which made those 4 permission changes and it started working.

[rjchauhan]

Yes I've followed every step in the upgrade guide and double checked :)

Laravel is on v5.8.9 and I've also tried installing composer dependencies by removing composer.lock file.

[driesvints]

@rjchauhan does this problem occurs for you on a fresh installation?

[rjchauhan]

Nope, Fresh installation works just fine! with same slack channel and same dependencies version.

[driesvints]

@rjchauhan then there's definitely something wrong with your specific installation. Have you updated the skeleton with all the changes from 5.8? Can you copy/paste your config/app.php config file?

I am having the same issue with an update from 5.7 to 5.8.

[ghost]

Hi; I started with fresh 5.8 Laravel installation. And received the mentioned exception. composer require laravel/slack-notification-channel fixed the problem in my case.

[driesvints]

I just tested this myself and this works fine. It seems there's something specific with your installs that's causing this not to work. @rjchauhan @lasselehtinen I really don't know what else can be done to figure out why it's not working for the both of you.

Please try to create an app and upload it to Github that recreates the problem so we can test it out. Let me know if you succeeded and I'll look into it.

[josegus]

Same here, i updated from 5.7 to 5.8, recently installed slack channel to log error and didn't work. I've changed the .env channel to slack, but nothing happend.

[josegus]

Nevermind, now is working, it was a problem with the level for each channel

[alasdairw]

Just noting - I'm having the same problem. Upgraded app, followed all the guides, same problem with Slack driver. If @lasselehtinen or @rjchauhan has had the "oh, that's what I did wrong" moment, I'd be really grateful if they could point me in the right direction!

[alasdairw]

In case anyone else turns up here from googling the same error:

php artisan config:clear php artisan cache:clear php artisan package:discover

fixed it for me.

[rjchauhan]

I figured out what the issue is. This package is getting discovered by auto discovery, but somehow it's not loading before AppServiceProvider. If I put \Illuminate\Notifications\SlackChannelServiceProvider::class (in app.php config file) before AppServiceProvider::class then it works fine, else not!

[driesvints]

@rjchauhan I don't have to do that and it works just fine

[driesvints]

Are you all using v2? Because v1 isn't supported on Laravel 5.8

[alasdairw]

@driesvints Definitely using V2 here - composer.json: "laravel/slack-notification-channel": "^2.0" and files on disk matches the repo at that version.

[alasdairw]

Having just tested pulling the changes I made last night through onto a different dev VM - it's only actually manually running php artisan package:discover that is to be required to pick up the Slack driver.

Not really a surprise, just wanted to note that the config/cache parts of what I posted above were not actually required.

[rjchauhan]

Yes, @driesvints I'm using v2. And on fresh Laravel 5.8 installation everything works fine. This issue only comes up on application where I upgrade from 5.7 to 5.8 😄

It's fixed by registering SlackChannelServiceProvider above AppServiceProvider and receiving notifications on slack as well.

[driesvints]

@rjchauhan you really don't need to do that so the problem is somewhere else

[rjchauhan]

Yes, I thought the same. Seems like it should be a problem somewhere in package auto discovery. or somehow slack channel service provider is not getting registered before application boots up.

[theriddleofenigma]

@driesvints I too have the same issue while upgrading the laravel framework version 5.7 to 5.8.

[theriddleofenigma]

I have installed v1.0.3. It works fine for me.

[pedmindset]

Having the same issue with laravel 6.4, i upgraded from laravel 5.8 sometime ago. I have tried everything here still not working.

[driesvints]

I'm currently using the slack driver perfectly in a live app. Please all, try a support channel:

Thanks.
