Hi team,
I am experiencing a critical issue with the Code (JavaScript) node in my n8n.cloud workspace. The node does not execute in any workflow and gets stuck in an infinite loading state, regardless of the workflow configuration or input data.
Symptoms:
-
Any workflow containing a Code node (JavaScript) hangs indefinitely when executed.
-
No result or error is returned; the node simply loads forever.
-
This occurs even with the simplest code, e.g.:
return [{ json: { ping: 'ok' } }]; -
The issue persists whether the Code node is run after a Manual Trigger or in test mode with no input.
-
Both “Run Once for All Items” and “Run Once for Each Item” modes are affected.
-
Other nodes (Set, Telegram, Google Sheets, etc.) work as expected.
Troubleshooting already performed:
-
Tested in different browsers (Chrome, Firefox, incognito mode).
-
Cleared browser cache.
-
Created new workflows from scratch.
-
Duplicated existing workflows.
-
Deleted all other active workflows and triggers.
-
Changed Code node configurations (mode, input data).
-
Tried different return values, including empty arrays.
-
The issue persists in all cases.
Environment:
-
n8n.cloud (cloud-hosted)
-
Workspace subdomain: soyolgalarina.app.n8n.cloud
-
Example workflow links:
-
Last attempted run: 11:19 (GMT+2), 01.10.2025
Request:
I have already performed all basic troubleshooting steps.
Could you please check the execution logs and the status of the Code node sandbox/interpreter, runners, and workers on your side for my workspace?
It seems likely that the issue is related to the server-side environment (sandbox, worker, or runner malfunction), as the problem occurs with any workflow and any code.
If you need access for debugging, I am ready to provide it.
Thank you in advance for your help!
Best regards,
Olga Larina
