Describe the problem/error/question
Hi there, so I have a complex workflow that is trying to perform an Airtable delete on a record – but if that delete operation fails, then it should update a status field on a different Airtable record. HOWEVER, the problem in the error path of the delete node, n8n throws an error saying that none of the earlier node state is available to the Mark Tech as Merge Failed4 node:
But the data is clearly listed in the first Airtable node right after the initial Webhook:
My question is: Is there any way to pass earlier node state information into the error path of any subsequent node?
What is the error message (if any)?
Can’t get data for expression
Share the output returned by the last node
