Describe the problem/error/question
Hi everyone. I stood up n8n for the first time a couple of days ago and am hosting it in a Docker container on my Synology NAS. I’m either having an issue with, or a misunderstanding of, the Compare Datasets node.
I have a single element coming into the node on both the A branch and the B branch, but the node shows that all the values in A only exist in A and not B and that the values in B only exist in B. However, as you can see from the screenshot below, the same values in A are also in B and vice versa.
In the screenshot, the left side is the input from the A branch and the right side is showing what the node is indicating is only in the B branch. I annotated the screenshot to show that what’s in A is also in B and vice versa. There are a total of 29 values on both the A and B sides and I know for a fact that they are the same, but the node is showing otherwise.
Is this a bug in the Compare Datasets node or am I misunderstanding how it works?
What is the error message (if any)?
