Creating embedded entities with the datastore command line tool

问题

I'm trying to use the Google cloud datastore command line interface to create arrays of embedded entities. I've figured out how to create an embedded entity value as follows:

{
    "properties": {
        "age": {
            "integerValue": "5"
        },
        "height": {
            "integerValue": "6"
        }
    }
}

and how to create an array value as follows:

{
    "values": [
        {
            "stringValue": "one"
        },
        {
            "stringValue": "two"
        }
    ]
}

But I haven't figured out how to add an embedded value to an array. For example:

{
    "values": [
        {
            "stringValue": "one"
        },
        {
            "stringValue": "two"
        },
        {
            "embeddedEntityValue": {
                "properties": {
                    "age": {
                        "integerValue": "5"
                    },
                    "height": {
                        "integerValue": "6"
                    }
                }
            }
        }
    ]
}

gives the error: "One or more values in this array doesn't look right. If you include values, make sure they are Datastore array values in JSON format."

I believe embeddedEntityValue should be changed to entityValue. Below is an example that shows an Array field with two embedded entities:

{
  "values": [
    {
      "entityValue": {
        "properties": {
          "areaCode": {
            "stringValue": "40"
          },
          "countryCode": {
            "stringValue": "91"
          },
          "subscriberNumber": {
            "stringValue": "2722 5858"
          }
        }
      }
    },
    {
      "entityValue": {
        "properties": {
          "countryCode": {
            "stringValue": "91"
          },
          "subscriberNumber": {
            "stringValue": "6666 0000"
          },
          "areaCode": {
            "stringValue": "80"
          }
        }
      }
    }
  ]
}
