DAM Metadata Writeback Workflow executing for a removed node

marissaw9851252 15-10-2015

We are overriding the "Product Assets Upload" step in the DAM Update Asset because the product ids do not follow the supported naming convention for the Product Photo Shoot Project.  In this step, we move individual assets or assets in a zip file to the proper product folders that were created when the shotlist csv is uplaoded. The assets are originally uploaded to the content/dam/projects/{YOUR PROJECT NAME}/incoming folder before they are moved to the correct content/dam/projects/{YOUR PROJECT NAME}/incoming/{Product ID/sku} folder.  After they are created in the new folder, the original node is removed.  For some reason, the DAM Metadata Writeback workflow is firing after the DAM Update Asset workflow with the old payload path(i.e. - content/dam/projects/{YOUR PROJECT NAME}/incoming/Test Photoshoot.zip) and errors are being logged and the DAM Metadata Writeback workflow is ending up in a STALE state because that node has already been removed.  Below is an example of the errors being logged.  We do not know why DAM Metadata Writeback is being triggered since the Event Type on the Launcher is Node Modified and not Node Removed. Why is this workflow firing for a node that no longer exists?  What is triggering this and how can we correct it?
