BUG: Working with large dataset results in Item Lists Node erroring with "Couldn't find the field in the input data" even though it exists

Describe the issue/error/question

When working with a large dataset in the Item Lists node, I can not split out a large array of data because it results in the field not being found:

What is the error message (if any)?

Couldn’t find the field in the input data even though it clearly exists

Please share the workflow

Share the output returned by the last node

Information on your n8n setup

  • n8n version: 0.201.0
  • Database you’re using (default: SQLite): Postgres
  • Running n8n with the execution process [own(default), main]: own
  • Running n8n via [Docker, npm, n8n.cloud, desktop app]: k8s

Hi @joeldeteves, there’s a good chance just one of your items (probably not on the first page) doesn’t have the property you are trying to split. Perhaps you can use an IF node before your Item Lists node checking the logs field isn’t empty?

I think you’re right. The message confused me because it said it couldn’t find the field itself.

Sorry for the confusion

HI @joeldeteves, no problem at all. Tbh, I find this behaviour a bit confusing myself and have suggested changing this internally (as in don’t have the Item Lists node fail if some items don’t contain the field to split out).
