I figured out that if you "Exclude Saved Lead lists" in your nav search filter. It will error out in clay if you try to upload it. Super annoying.
You can use the enhanced table exclusions feature instead, which provides a more reliable way to exclude saved leads: 1. Go to "Add Table" and select "Find Companies" or "Find People" 2. Look for the "Exclude" section 3. Select your saved leads table as the exclusion source 4. Choose the appropriate matching criteria (like social URL or domain)This will automatically exclude matches from your reference table while avoiding errors in the upload process.
