A little known issue that you might see crop up from time to time is when you go to download your zip file from the customizations section of the USD you are immediately presented with an error that the “Record is Unavailable” even though it clearly is.
This can be incredibly painful because sometimes all you need to do is update a configuration and redeploy.
Getting to your file is possible, but requires a few extra steps.
Using Advanced Find, search against the Annotations/Notes that you are looking for (in my case USDQueueControl.zip.
Once you’ve located the exact record, open it to view directly in your browser.
Once in this view, click on the filename “USDQueueControl.zip” in my case and your file will automatically start downloading.
To update your pre-existing attachment, remove it and re-upload your new file.
