You must add either a name or ID for your "{object_type}" before you can complete your upload. Please add a name or ID and try again.

Why did this happen?

This error occurs when an ad object does not have an ID or name specified as an identifier in your spreadsheet.

How do I fix it?

When importing a campaign/ad set/ad in Excel, make sure that you include an ID/name as an identifier.
