InsertOne doesn't populate result error

[derekperkins]

When I get an error back from InsertOne, I'm hoping to have the result include the structured error response, but it doesn't. All I get is an error string with the json packed into it. Is that expected behavior? Should I be unmarshaling the error string myself to see if it successfully goes into []SalesforceErrorMessage?

[
  {
    "message": "duplicate value found: MyAccountId__c duplicates value on record with id: 001Vr012300m4eGCIAY",
    "errorCode": "DUPLICATE_VALUE",
    "fields": []
  }
]
