Hi n8n Community,
I recently updated n8n after being 5 versions behind, and now my Slack integration and workflows are not functioning properly. Here’s a breakdown of the issue:
What’s Working:
My old workflow (created before the update) with a Slack trigger still works fine. (See Screenshot 1)
The Slack bot is properly integrated into the channel.
Live workflows (older ones) are executing as expected. (See Screenshot 2)
What’s Not Working:
New workflow with Slack trigger does not respond to messages, even though settings match my working workflow. (See Screenshot 5)
No execution logs appear in the workflow history for the new workflow. (See Screenshot 6)
When switching to testing mode, it takes forever to execute—this happens across all agents and workflows.
The Slack bot is added to the channel, yet it does not reply to messages.
Screenshots for Reference:
Screenshot 1: Old workflow working fine.
Screenshot 2: Execution log of the working old workflow.
Screenshot 3: Slack trigger settings in my working old workflow.
Screenshot 4: Slack trigger settings in my new workflow (same settings as old one).
Screenshot 5: No response from Slack bot in the channel after sending a message.
Screenshot 6: No execution recorded in the workflow history for the new workflow.
Steps I’ve Taken to Debug:
Double-checked that the Slack app has all necessary permissions.
Compared Slack trigger settings in the old and new workflows (they are the same).
Restarted n8n, cleared cache, and refreshed workflows.
Checked logs—no execution history for the new workflow.
Has Anyone Experienced This?
Could this be a breaking change in recent updates affecting Slack triggers or execution handling? Any help or insights would be greatly appreciated!
Thanks in advance!
