Hi, I have a question. Currently, I have a node that performs a number increment. I am setting this node with an initial value of 0 and want to increment a number in it.

My node component:

Example of my code:  
Previously, I used the following, and it worked perfectly:  
`$item(0).$node["Set counter"].json["counter"]`

I’ve tried other ways, such as:  
`$('Set counter').first().json.counter += 1 // Increment counter`

But it didn’t work.  
The value is changed, but the state is not maintained. Instead of being altered, it remains at only the value of 1

For the workflow I am working on, this seems to be the only solution. I tried a few others, but they didn’t work. I need to change the value of the node directly using custom node scripts

## Information on your n8n setup

- \*\*n8n version: 0.224.2
- \*\*Database (default: SQLite): postgres
- \*\*n8n EXECUTIONS\_PROCESS setting (default: own, main): default

My old code worked, after the update n8n version it didn’t work:

```auto

items[0].json.lastNode = false;

// Increment counter
$item(0).$node["Set counter"].json["counter"] += 1;

// Check if the current node is the last node
const lastNode = $items("calculate-voucher-quantity", 0, 0).length <= $item(0).$node["Set counter"].json["counter"];

// If it's the last node, set lastNode to true
if (lastNode) {
  items[0].json.lastNode = true;
}

// Return the items array
return items;

```

I was able to solve it. 🙌😅  
I used the variable $runIndex, and the code looked like this:

```auto
const isLastNode = $items("node_name_here", 0, 0).length <= $runIndex + 1

items[0].json.lastNode = isLastNode

return items;

```
