Array variable getting depulcates

I have the following flow that creates, populates, and then posts the contents of an array.

  1. Initialize Empty Array
  2. HTTP GET Items
  3. For Each Item
    1. HTTP GET Item Details
    2. Append to Array
  4. HTTP POST Array

When looking in the run history, I can see two items returned in Step 2 and the For Each has 2 iterations. However, when looking at Step 4, I'm seeing 3 items returned in the array where the first item is duplicated and added twice.

 

Any advice on how I can troubleshoot?

Hey @jgalus 

 

I am not sure why duplicate items are being returned but you can use - 

 

union() to remove duplicated items - For details see https://www.flowjoe.io/2020/12/17/remove-duplicates-from-a-power-automate-array-with-one-action

Unfortunately, if there are legitimate duplicates I'd need to include those.
