What causes this error?

You picked an optimization goal (like ‘Purchases’ or ‘Value’) that fundamentally clashes with the chosen Campaign Objective (like ‘Brand Awareness’).

How to fix it

Align your data! If your core Objective is ‘Traffic’, your target optimization must generally be ‘Link Clicks’ or ‘Landing Page Views’. Adjust your payload or UI drop-downs to ensure logical synchronization.
