ValueError: too many values to unpack (expected 2) when using SlackPostCurl PostProcessor about autopkg-recipes

[notverypc]

What happens if you change the command from:

autopkg run -vvv Skype.munki --post="com.github.notverypc.autopkg-recipes.postprocessors/SlackPostCurl" --key "webhook_url"="https://hooks.slack.com/services/123456789/123456789/123456789"

To, without the "" around webhook_url:

autopkg run -vvv Skype.munki --post="com.github.notverypc.autopkg-recipes.postprocessors/SlackPostCurl" --key webhook_url="https://hooks.slack.com/services/123456789/123456789/123456789"

Changing the quoting made no difference.

🤔 Can you add the channel key to the command - even if you're not overriding it.

autopkg run -Skype.munki -post="com.github.notverypc.autopkg-recipes.postprocessors/SlackPostCurl" --key webhook_url="https://hooks.slack.com/services/XXXXXXX" --key slack_channel="testing"

[ggeerraalldd]

Same error, but it did not post to Slack (no 'testing' channel)
The webhook_url I use points directly to my user in Slack.

           'slack_channel': 'testing',
           'webhook_url': 'https://hooks.slack.com/services/123456789/123456789/123456789'}}

Can you post the command you used and I'll look into it further.
"The webhook_url I use points directly to my user in Slack." Are you posting direct to you not a channel?

[ggeerraalldd]

autopkg run -vvv Skype.munki --post="com.github.notverypc.autopkg-recipes.postprocessors/SlackPostCurl" --key webhook_url="https://hooks.slack.com/services/123456789/123456789/123456789" --key slack_channel="testing"

I am posting directly to myself and not a channel. I've used that webhook_url with AutoPkgr and your original Slacker post processor (which still works).

[notverypc]

Thanks - I'll have a look into this.
I managed to reproduce the error when I just used the webhook_url but after adding slack_channel it ran without errors.

I'll have a proper dig, probs something simple that I've missed.

[ggeerraalldd]

I went in to Slack settings and changed my webhook URL from a deprecated Custom Integration I set up in 2018 to one generated by the more recent Slack App method. That also made no difference.

[notverypc]

I've updated the postprocessor and it should resolve your issue 🤞

[ggeerraalldd]

I think that's closer, but I'm still getting an error. This time, it appears the error is for every recipe that doesn't have an update, so doesn't post to slack:

local variable 'json_data' referenced before assignment
Failed.

From a AutoPkg list of 61 recipes, 2 had updates and I received the error 59 times. That includes MakeCatalogs.munki recipe that runs at the end, and will never result in a download.

Attached are AutoPkg results of two consecutive runs, the first finds updates for the two recipes and posts to Slack without error, then the next run has no updates and errors out twice.

🤬 My bad - I'll dig into it in the morning- Sorry 🙏

[notverypc]

Should be working now - sorry for all the pain 🙏

[ggeerraalldd]

That ran error free on my AutoPkg test server. I changed my production server to use SlackPostCurl instead of Slacker so I'll see what happens on its next scheduled run.

[ggeerraalldd]

The full recipe list on my production server ran via autopkg-conductor.sh using SlackPostCurl as the post processor, and worked as expected!

Thank you so much for the bug fix. I appreciate all your effort. :)

[notverypc]

Pleased to hear it's working :)
Sorry for the pain :)
