如何在DynamoDB查询操作上指定多个条件？

var params = {
            TableName: "liveTraining",
            KeyConditionExpression: "#ContentId = :contentId and #CompanyId = :companyId and #Status=:status",
            ExpressionAttributeNames:{
                  "#ContentId": "ContentId",
                  "#CompanyId": "CompanyId",
                  "#Status": "Status"
                },
            ExpressionAttributeValues: {
                ":contentId": contentId,
                ":companyId": companyId,
                ":status": 'Active'
                }
        };
        return new Promise((resolve, reject) => {
          dynamoDB.query(params, function (error, response) {
            if (error) {
              console.log('Unable to fetch data', JSON.stringify(error, null, 2));
            } else {
              console.log('fetched data', response);
            }
          })
        });

当我使用AND运算符指定两个以上条件时，出现错误：

Unable to fetch data {
  "message": "Conditions can be of length 1 or 2 only",
  "code": "ValidationException",
  "time": "2019-04-12T06:53:34.766Z",
  "requestId": "MOE9FDN6I62NLROVPPTDMS5V2JVV4KQNSO5AEMVJF66Q9ASUAAJG",
  "statusCode": 400,
  "retryable": false,
  "retryDelay": 29.17802723976769
}
