N8N does not recognize the value of a field

Questions

Guys, I have a return that gives me a field, when I try to use it, it always returns “undefined” does anyone know why?
I understand that this field may or may not return the results, is that why? Since it’s not a field that always appears, I can’t use it?
The field with the error is the one from the last step:
{{ $json.customFields[1].enum_value.name }}

return data:

It looks like your topic is missing some important information. Could you provide the following if applicable.

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

hello @Pedro_Malaquias

it’s undefined because n8n will calculate it’s value from the first item. You can hover on the desired item to see if the expression becomes green.
