Unable to access nested data from a IF node

Questions
1

Hey n8n community,

Can anyone explain why this IF node data is not accessible when I use a $ifEmpty() expression?

The node returns undefined even though there is data and if I access without the $ifEmpty() expression the data is read without issue.

Steps

  • I’m checking if the user exists in my DB then using the IF node to funnel based on the outcome.
  • If TRUE, the output is an empty array, therefore I thought the $ifEmpty() would be perfect for this as if FALSE the node branches to a create user node.
  • At the stage where I’m getting the error there will always be data returned either from the TRUE OR FALSE outcome.
  • I’ve even tried just declaring $json.id since there will always be an id but this also causes undefined to be returned.
  • I’ve also tried accessing the node directly by name
