Research direction
Investigate the broker listing endpoint (/brokers) to understand how disk usage data is aggregated. Look for filtering logic that excludes brokers with null disk usage. Modify the service layer to include all brokers regardless of disk usage status. Ensure the fix doesn't break existing functionality by checking any related tests.
