Bug Description

In n8n v2 (which utilizes the task runner to execute Code nodes), workflows containing a Code node run normally during manual debugging. However, when the workflow is published and triggered in a production environment (e.g., via Webhook, Schedule/Timer, or Form trigger), the Code node unexpectedly times out.

This behavior appears to be related to issue #23553.

To Reproduce

1. Deploy and run n8n using the docker-compose.yml configuration provided below.

         },

           "language": "pythonNative",

       }
     ],
     "pinData": {},
     "connections": {
       "On form submission": {
         "main": [
           [
             {
               "node": "Code in Python",
               "type": "main",
               "index": 0
             }
           ]
         ]
       }
     },
     "active": true,
     "settings": {
       "executionOrder": "v1",
       "binaryMode": "separate",
       "availableInMCP": false
     },
     "versionId": "007c0605-565b-4fcc-be1f-8b213b2e45e6",
     "meta": {
       "instanceId": "2e7d2c03a9507ae265ecf5b5356885a53393a2029d241394997265a1a25aefc6"
     },
     "id": "D58W8IzrZeL71Cme",
     "tags": []
   }

3. Trigger the workflow using the Form Trigger node:

   • Test Environment: Submitting via the Test URL runs successfully.

   • Production Environment: Submitting via the Production URL results in a timeout at the Code node.

Expected behavior

The Code node should execute successfully without timing out, regardless of whether the workflow is being tested manually in the UI or running in a published/production state (triggered via Webhook, Timer, or Form).
