AMS/ACE Ocean Error code 299 INVALID B/L IN B04/N9

Info
If you receive a NVOCC AMS bill rejection "299 INVALID B/L IN B04/N9" then this means that the corresponding carrier has filed their AMS manifest with wrong bill type (Regular Bill).
Notes
Carriers who files the Regular Bill type is telling CBP that there is no freight forwarder involved in this shipment so CBP is not expecting any NVOCC AMS BL submission hence, rejecting the Bill of lading. 
RESOLUTION:
Alert
Please advise the carrier to amend their bill type to MVOCC or MVOCC (FROB) BL. When the carrier sends the change  and got it accepted then the NVOCC user can then send the NVOCC AMS BL as an ADD.
