If the Security Group has "Managed Prefix List" allowed for specific traffic, Flightpath shows it as fail since it is unable to read the PL (prefix List) in the SG-.
This is currently a limitation with Aviatrix FlightPath.
- Managed Prefix List defined on AWS Console > VPC > Managed Prefix List
- "Managed Prefix List" is used as Source in SG- on AWS
- Flightpath shows Security Group as FAIL and does not list the pl-xxxxxxx (prefix-list) in the Security Group
