Recurring Crashes and Restarts in N8N Workflow with Microsoft Outlook Node

Describe the problem/error/question


We have an issue. Every time we launch a specific workflow on N8N, our N8N crashes and restarts miserably.

We suspect a bug in the Microsoft Outlook node. If we set the limit to 1 and add this filter: contains(subject, ‘Attend the Rugby World Cup final!’), bam! N8N goes on strike and restarts the pods.

Could you take a look for us? Below is a workflow to reproduce the crash, but be careful, not on your prod machine! Ahah, we don’t want any collateral damage! :smile::hammer_and_wrench:

What is the error message (if any)?

No specific error message available at the moment.

Please share your workflow

Share the output returned by the last node

Information on your n8n setup

  • n8n version: 1.5.1
  • Database (default: SQLite): SQLITE
  • n8n EXECUTIONS_PROCESS setting (default: own, main): default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
  • Operating system: Kubenetes

Hi @Twinki :wave:

Well, I tested this and didn’t have my n8n explode :joy: Though I did only send myself two test emails, one to match each condition to my Outlook account. I didn’t have any issues with the limit set to 1, or running this workflow… can you let us know a little bit more about what that sub-workflow does? Does it only crash when it hits the Outlook node?

If you could share some logs with us, that would also be super helpful!
