[Prakash Sivagurunathan]

I created a REST API for sap hana connector and while trying POST, the REST call failed with HTTP Error Code 500.

Response Body:

{
  "error": {
    "name": "Error",
    "status": 500,
    "message": "invalid sequence: CONTACTSeq: line 1 col 26 (at pos 25)",
    "code": 313,
    "sqlState": "HY000",
    "level": 1,
    "position": 25
  }
}

where  CONTACT is my model name.

I tried PUT, GET and DELETE, and it worked fine. only POST is failing with above error.
