Error "Invalid Request Parameters" When Submitting Feed "POST_FBA_INBOUND_CARTON_CONTENTS"

[zaki-siddiqui]

I have been attempting to submit a feed for "POST_FBA_INBOUND_CARTON_CONTENTS." I successfully created a feed document and constructed a feed with my XML (generated from the given XSD), and the response was 200 OK. However, when I try to create a feed with the appropriate parameters, I consistently receive the error "Invalid request parameters." Has anyone successfully created a "POST_FBA_INBOUND_CARTON_CONTENTS" feed with an XML file? If so, please guide me accordingly.

My XML file
