一个或多个参数值无效：商品状态码：400，请求ID：71CT中缺少密钥ID

I have made a table "Blog" in dynamodb.

I want to insert the 2 parameters "title" and "content" in it which I am fetching from a HTML form.

The parameters "blogContent" and "blogTitle" seem to be valid when I print these 2 in the console.

But when I am inserting them in the table i get the error:

"One or more parameter values were invalid: Missing the key id in the item status code: 400, request id: 71CT5IPM1SIDKSDVUGWGUCSJ77VV4KQNSO5ZAMVJF66Q9ASUAAJG"

type Item struct {
    id                 int
    content            string
    bodycontentversion string
    claps              int
    comments           int
    imageid            int
    title              string
    views              int
}


func awsblog() {

    sess, err := session.NewSession(&aws.Config{
        Region: aws.String("us-east-1")},
    )

    svc := dynamodb.New(sess)

    item := Item{
        id:                 1234,
        content:            blogContent,
        bodycontentversion: "abcd",
        claps:              5,
        comments:           10,
        imageid:            1234,
        title:              blogTitle,
        views:              10,
    }

    av, err := dynamodbattribute.MarshalMap(item)
    if err != nil {
        fmt.Println("Got error marshalling new item:")
        fmt.Println(err.Error())
        os.Exit(1)
    }

    tableName := "Blog"

    input := &dynamodb.PutItemInput{
        Item:      av,
        TableName: aws.String(tableName),
    }

    _, err = svc.PutItem(input)
    if err != nil {
        fmt.Println("Got error calling PutItem:")
        fmt.Println(err.Error())
        os.Exit(1)
    }

    fmt.Println("Successfully updated '")
