Hi Team,
MX304 upgraded to Junos 24.4R1-S2.9, since then we noticed there is a lot of route record lookup failures / AS lookup failures for the inline-jflow.
Here is the Route Record Lookup Failures in MX304:

It is a Day-1 issue for Inline Jflow feature on AFT based Line cards.
Trigger : Insert an Explicit Default Route(either BGP Injected or create static route manually or in any other form) where the traffic should get forwarded with this route.
Impact: The inline Jflow feature will not report right AS information in the exported IPFIX Records.
Fixed under PR1901369
