Issue with API /otvimbas/pf01_inb_ingest - Exception on Sender Infomation

SLUCASJEAN

Hello

we used the Json example and called the API and even though the sender information is optional and free text, we get an exception raised by this method :

"

method IF_SXML_READER~NEXT_NODE
    by kernel module FXKMSRD_NEXT_NODE FAIL.
  endmethod.

"

We have then the same for the receiver information.

Is this related to the version of SAP S4 ?

or is there a bug in the API itself ?

Thanks

Sébastien
