Help! My workflows are gaslighting me - they say they succeed but nothing happens!"

[Kal_Crouve]

Hey n8n team, I’m about to lose my sanity over here. My mission-critical workflow is straight-up LYING to me:

Workflow Path: API → Data Transform → Google Sheets Update → Slack Notification

What Happens:

Everything shows green checkmarks

Slack gets success notifications

But when I check Google Sheets… NOTHING CHANGED!

Kicker: The exact same workflow works perfectly when I manually test it!

Environment Details:

n8n 1.33.2 on Google Cloud Run

Using OAuth2 for Google Sheets

Triggered by Cloud Scheduler every 15 mins

What Makes This Extra Maddening:

Only fails on automated runs (manual executions work)

No errors in ANY logs (n8n, Google Cloud, nothing)

Already tried:

Doubling timeout limits

Adding manual delays between nodes

Creating fresh OAuth credentials

Sacrificing my favorite coffee mug to the tech gods

Please tell me:

Why is n8n pretending to succeed when it fails?

How do I catch these “fake success” cases?

Is there ANY way to get truth out of my workflows?

I’m begging you - this is making me question reality itself!

Your n8n version is more than a year old - start by updating to the latest version.
