How does loop work?

[Evgeniy_Orel]

Describe the problem/error/question

I really don’t understand how the Loop node works, I’ve read so many topics here, but I haven’t found a solution to the problem. I don’t even know how to describe it, it would be better to show it on video, but I don’t see the possibility to attach it here, so I’ll upload it to YouTube https://youtu.be/V1LISoRkas8

In short, the loop changes its behavior every time in a new way, when I want to test the loop to get data from the previous step, it returns a response only depending on the next steps, that is, for testing I have to disable all subsequent steps.

And after each test, the data is reset and I need to do all the steps again, why isn’t the data from the previous step simply used?

What is the error message (if any)?

no errors

it seems that you just get one item, you should add some input data to test the loop node

Try cleaning the current execution data and try it. Also, in a lot of cases, the loop node is not needed as n8n process already items one by one.
