Hi ​@Troy Tessalone, 

This is how the Step 2 is configured:

Things to check/try:

• Make sure all required fields have values
  • Add a Filter step to check
    • Help: https://zapier.com/apps/filter/help
• Compare successful VS unsuccessful Zap Runs to see if you can identify the difference that is causing the error
• Feedback from AI

+1 - I have exactly the same issue on all my Slack Zaps. They’re working 90% of runs, but hitting lots of failures with the error ‘This Slack step hit an error
Error while hydrating data from Slack: Error from Slack: message_not_found’ 

Has Slack changed its API config somehow?

Here’s what the log looks like when I try to rerun it:

Zap trigger: Slack - New Message Posted to Private Channel

This is an instant Zap trigger type that fires from a webhook sent from Slack.

The webhook data payload often only contains a subset of information about the Slack message and that is to be paired with a Slack API call to get the full message info.

The Slack Zap trigger is configured to do that API request behind the scenes.

For the Zap Run errors:

• there’s a chance that the message was deleted so the Zap triggered to run from the webhook, then could not find the message when attempting to do the API request
• there’s a chance that the message in the private channel is not accessible by the connected app account using the Slack API request

You should update your slack connection to the latest version. I observed the same issue and it solved the problem
