This seems to be the fix for almost every node I make… rerunning the workflows and then:
The expression {{ $('Notion').item.json.url }} is incorrect because it uses .item, which can cause issues. The correct expression should be:
{{ $('Notion').first().json.url }}
This ensures that the expression retrieves the first item from the Notion node.
Slack node ran successfully, did my solution help resolve your issue?
Is there any best practices or how to avoid this over and over with each node?
It looks like your topic is missing some important information. Could you provide the following if applicable.
This is a simple webhook from a purchase a client makes.
Then trying to automate all the onboarding steps, invites, folders, files etc.
Just started on n8n yesterday so give me all the harsh feedback you have.
Welcome to the community @marsattack204 !
Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.
```
<your workflow>
```
That implies to any JSON output you would like to share with us.
The reference of an item in the previous nodes (not immediately preceding the current one) by means of .item. is the default one. It implies an automatic inference of the linked item. It normally works fine until the data flow gets split with nodes like If and Switch or Merged. In this case n8n might need some help from you to point out at the actual item in the node prior the data branching.
The solution would be using the methods like first(), last(), etc. You still could use .item. but you need to make sure there is no data splitting between the current and the referenced nodes. That also might imply passing the data you need to that referenced node from the actual source of the data.
If you want to dig deeper into the mechanism of the linked items you can read the following docs:
