N8n error: Cant determine item

Questions
1

Hi guys, d

I’m running into a recurring issue in one of my n8n workflows where a later node cannot correctly access data from an earlier node. Instead of returning the expected value, n8n throws the following error:

“Multiple matching items found”
and
“ERROR: Can’t determine which item to use.”

I refer to earlier nodes and the current node cannot retrieve the data:d

So far, my workaround has been to add an additional Code node to manually re-fetch or re-map the data I need — but this doesn’t feel like a clean or recommended solution.

What I’m Looking For

I’d like to know:

  1. What is the best practice for handling this situation?
    When a node earlier in the chain outputs multiple items, and a later node needs to reference a specific one.

  2. Is there a better alternative than adding an extra Code node just to restructure the data?

Thank you for your help!!

the error message actually pointed out the problem

in Get Survey node at the bottom of the image you have 2 items and in your current one you end up with one. so you current single item reference 2 items in the GET Surevy node and you can not use {{ $(‘Get Survey’).item.json }} beacause item is an array of two items you can reference the first one by suing {{ $(‘Get Survey).first() }}

but why you have 2 surveys at the start and then return a single item down the road
