SharePoint

ItemConflict — Save Conflict

Your changes conflict with those made concurrently by another user (or workflow).

Root cause

You tried to update a SharePoint list item (via UI, REST, or Power Automate) but the item was modified by someone else since you first loaded it.

How to fix it

  1. In code, fetch the latest item metadata and ETag before submitting the HTTP PATCH request.
  2. In Power Automate, add a delay or retry policy, as another flow might be simultaneously updating the same item.
