Omniture Data Warehouse API Not Allowing 'hour' Value for Date_Granularity
===

When using the Omniture Data Warehouse API Explorer ( https://developer.omniture.com/en_US/get-started/api-explorer#DataWarehouse.Request ), the following request provides an 'Date_Granularity is invalid response'.  Does anyone have experience with this?  The API documentation ( https://developer.omniture.com/en_US/documentation/data-warehouse/pdf ), states that the following values are acceptable: "none, hour, day, week, month, quarter, year."


    {
	"Breakdown_List":[
		"evar14",
		"ip",
		"evar64",
		"evar65",
		"prop63",
		"evar6",
		"evar16"
	],
	"Contact_Name":"[hidden]",
	"Contact_Phone":"[hidden]",
	"Date_From":"12/01/11",
	"Date_To":"12/14/11",
	"Date_Type":"range",
	"Email_Subject":"[hidden]",
	"Email_To":"[hidden]",
	"FTP_Dir":"/",
	"FTP_Host":"[hidden]",
	"FTP_Password":"[hidden]",
	"FTP_Port":"21",
	"FTP_UserName":"[hidden]",
	"File_Name":"test-report",
	"Metric_List":[	],
	"Report_Name":"test-report",
	"rsid":"[hidden]"

	"Date_Granularity":"hour",
    }

Response:

    {  
	"errors":[
		"Date_Granularity is invalid."
	]
    }
