BUG: Faulty Javascript being implemented in the Code node after update to v0.222.3

Describe the problem/error/question

Yesterday, i upgraded from v0.219.1 to latest (v0.222.3)
Since then, one workflow (checked so far) is erroring out in the code node, in a simple JS operation.

Please share your workflow

Example of the code in question:

Share the output returned by the last node

I checked in MDN to see whether the hasOwnProperty function has been deprecated. But that’s not the case either (Object.prototype.hasOwnProperty() - JavaScript | MDN).

As seen in the screenshot:

  • Line 6 shouldn’t have executed at all

(Correct) Output as seen in v0.219.1 :

It’s rather troubling that basic JS is breaking down.

Information on your n8n setup

  • n8n version: latest (0.222.3)
  • Database (default: SQLite): Postgres
  • n8n EXECUTIONS_PROCESS setting (default: own, main): main
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
  • Operating system: Ubuntu

What’s the error?

Did you mean to check for the update property twice?

This is N8N-6333 internally buddy.

Hi all.

Has there been any update on this, in any of the subsequent versions?


I checked again with the release v0.226.0.

Same: faulty output.

@shrey-42 Thanks for reporting the issue, and also for including the test workflow; it was very helpful for debugging.

This is being addressed in PR 6124 , and will hopefully be included in the next release.


New version [email protected] got released which includes the GitHub PR 6124.
