Error of Deserialize with CreateAsync when salesforce return error

[Oberown]

Hello,

When I use CreateAsync and salesforce return a error.
Salesforce return this

{
    "hasErrors": true,
    "results": [
        {
            "referenceId": "Id 1",
            "errors": [
                {
                    "statusCode": "STRING_TOO_LONG",
                    "message": "TotoId: data value too large: AzertyAzerty (max length=5)",
                    "fields": [
                        "TotoId__c"
                    ]
                }
            ]
        }
    ]
}

But the error message is parsed in ErrorResponses , but is not the good format.
It make an exception of Deserialise not an exception with the salesforce message.

private static ForceException ParseForceException(string responseMessage)
        {
            var errorResponse = JsonConvert.DeserializeObject<ErrorResponses>(responseMessage);
            return new ForceException(errorResponse[0].ErrorCode, errorResponse[0].Message);
        }

You're welcome.
