A javascript code is not running since last update. The code doesn’t look wrong on my side so I’m a bit lost.
ERROR: Cannot read properties of null (reading ‘0’) [Line 10]
Hey @Vincent_Bonjean,
Have you tried using a code node instead of the function node to see if that works?
Looking at the code I would assume there is something missing on the input but it looks like it is there so it is a bit odd.
If you downgrade to the last version you were using does it work again?
Hi Jon, thanks for your return.
Tried to use a code node but I get the following error (not the first time since last update)
ERROR: Unknown top-level item key: index [item 0] Access the properties of an item under .json, e.g. item.json
Also tried to downgrade but I think I missed to update since a few months so the lowest isn’t working too.
Hey @Vincent_Bonjean,
That is interesting a downgrade should have resolved it if you went back to the version it was on. I wonder if maybe there is something else going on with the data.
Can you share the webhook data so we can have a play?
sure

Hey @Vincent_Bonjean,
Oddly for me that is working 
or it is not returning an error anyway. It could be an issue with the Item / Items alias not working which I think was fixed in 231 but for now try the below, I have updated the function nodes to use a Code node instead.
Hi @Jon, this is very strange indeed. Just retried using your node and on the 0.230.2 version but still have the same issue popping up…
ERROR: Unknown top-level item key: index [item 0]
Access the properties of an item under `.json`, e.g. `item.json`

Which next steps would you advise to troubleshoot this ?
Hey @Vincent_Bonjean,
Did you try with the same test webhook data that you previously shared? Could you try with the 231 release and see if that works for you?
Retried using 231 with the same output but still have the same issue.

ERROR: Unknown top-level item key: index [item 0]
Access the properties of an item under `.json`, e.g. `item.json`
Any shots ?
If I use your example json with the workflow I posted before it is working, Have you tried pasting in the workflow I shared?
I just changed the last node in my previous attempt but duplicating yours worked indeed but it’s very odd as you just changed the last node right ?
Could be great to understand the root cause of this issue if you have any clue ?
Many thanks for your help @Jon
Hey @Vincent_Bonjean,
I changed all of the nodes 
try using the full workflow and see if that helps.
oh I see I will dive in to see the changes. The full workflow re-works as expected. Many thanks!
