Dear team,

How can I send a multipart postman request containing a file and a json object like this?

Content-Type: multipart/form-data; boundary="----=_Part_2dfwfwerwe"
Content-Transfer-Encoding: binary
Content-Disposition: form-data; name="metadata"
Authorization: Bearer XXXXXXXXXXXXXXXXXXXXX
Transfer-Encoding: chunked

------=_Part_2dfwfwerwe
Content-Type: multipart/form-data
Content-Transfer-Encoding: 8bit

{
"documentko": {
"userId": "XXXXXXXX",
"imageko": {
"fileFormat": "PDF"
}
}
}

------=_Part_2dfwfwerwe
Content-Type: application/octet-stream; name=
Content-Transfer-Encoding: binary
Content-Disposition: form-data; name="document"; filename=""

When I trying I receive a message like this:

"RESTFaultCode" : "rest:Server" ,
"Reason" : "WebService Processing Exception" ,
"detail" : "Invalid request"

Thanks you!
