There could be a few reasons why you're not getting any fields back when using the "Enrich Person" action with Apollo integration:
1. Insufficient input data: Make sure you're providing enough identifying information. The action accepts various inputs like First Name, Last Name, Email Address, Company Name, or Company Domain.
2. API key issues: Your Apollo API key might be invalid or lack necessary permissions.
3. Integration error: There might be a temporary issue with the Apollo API integration.
To troubleshoot:
1. Double-check your input data and ensure it's accurate.
2. Verify your Apollo API key's validity and permissions.
3. Try refreshing your browser (Cmd/Ctrl + Shift + R).
4. Run only the affected rows using the error retry option.
If the issue persists, you may need to request human assistance for further investigation.
