Hey, I’m really struggling to get this new code node to work, it just seems like a step backwards in my eyes. Alot more complicated to do simple things, specifically referencing a previous nodes output. You cant use $input.X.X to reference the bits you need, how we used to do it via $json.x.x I j…

Nope, this new code node really doesnt want to play nice with me at all. in “Run once for all items” const html = $input.first().json.html; works const html = $input.all().json.html; doesnt neither does const html = $input.all(); [Mad Angry GIF – Mad Angry Angry Girl – discover and share GIF…

also the documentation doesnt help either, i think there is a fundamental lack of examples are troubleshooting on there, it works completely differently to the function nodes and it just seem so much more difficult to get simple things to work. perhaps I’m missing something here, this shouldn’t be t…

Sorry to hear that you have problems. I hope the following makes it clearer. $input.first() is the first item of the input. So it is an object with looks roughly like this for your example above: { json: { html: '....', } } $input.all().json.html are all the incoming items and is so an a…

ok so how do i reference in a code node to point to the “xxxx” [ { "html":"xxxx" }, { "html":"xxxx" }, { "html":"xxxx" } ] In the code node I need it to run the script against each incoming item from the previous input.

Which “xxxx” as there are 3 of them? The first one would be: $input.all()[0].json.html // or $input.first().json.html The second one: $input.all()[1].json.html And the last/third one: $input.all()[2].json.html // or $input.last().json.html Or you can, for example, combine all of them into one…

i need to reference them all one by one for the code node to process the values etc bear in mind I don’t know how many there will be as the input

In this case you can use the example that is directly given in the Code-Node when you create a new one. For “Run Once for All Items” it looks currently like this: // Loop over input items and add a new field // called 'myNewField' to the JSON of each one for (const item of $input.all()) { item.j…

If I change it to run once for each item const html = $input.item.json.html; I get this error: ERROR: Unknown top-level item key: 0 [item 0] Access the properties of an item under `.json`, e.g. `item.json` the input from the node before is: [ { "html":"html is here already" }, …

@RedPacketSec I just tried to reproduce your error and think I found your problem. Might it be that you return $input in your code node? The code node in Run once for each item mode expects you to return $input.item. Here’s a quick workflow that I used to show this: The err…

ok, so that sort of helps, now i need to massage that into my massive script. Thank you that gives me something to work with, much appreciated.
