DynamoDB不保存我的项目

Question

当我的桌子上都有“哈希”和“范围”键时，我的项目无法保存。如果我只有哈希值，它就可以工作。

我的表在我的serverless.template文件中定义

"TestTable" : {
    "Type" : "AWS::DynamoDB::Table",
    "Properties" : {
        "TableName" : "Test",
        "AttributeDefinitions" : [
          {"AttributeName" : "UserId", "AttributeType" : "S"},
          {"AttributeName" : "Id", "AttributeType" : "N"}
        ],
        "KeySchema"            : [
          {"AttributeName" : "UserId", "KeyType" : "HASH"},
          {"AttributeName" : "Id", "KeyType" : "RANGE"}

        ],
        "ProvisionedThroughput" : {
          "ReadCapacityUnits" : 3,
          "WriteCapacityUnits" : 3
        }
    }
}

我的功能如下：

    public async Task<APIGatewayProxyResponse> CreateAsync(APIGatewayProxyRequest request, ILambdaContext context)
    {
        var test = new Test();
        test.Id = 1;
        test.UserId = "Test";

        await DDBContext.SaveAsync<Test>(test);

        var response = new APIGatewayProxyResponse
        {
            StatusCode = (int)HttpStatusCode.OK,
            Body = "foo",
            Headers = new Dictionary<string, string> { { "Content-Type", "text/plain" } }
        };

        return response;
    }
