Describe the problem/error/question

I have a list of 60 items fetched from an API source. I’m using the Loop Over Items node to process each item individually in a loop. Here’s an overview of the workflow:

Everything works fine initially. However, after looping through the 60 items, the Loop Over Items node unexpectedly starts additional batches, each doubling in size: first 60 items, then 120, then 240, then 480, and so on.

These unexpected additional loops consume a significant amount of memory. If the memory limit allows, it continues until it completely clogs the RAM.

Hi @Mohdlatif,

Could you try removing the connection between

  1. “Replace Me” and “Reviews Exists”
  2. “Replace Me” and “Loop Over Items”

In general you should not connect the Loop Over Items node’s “done” output back to its input.

Hope this helps!
