描述

**Describe the bug**
Failed to write the pre-created aligned timeseries through the MQTT API.But the unaligned timeseries is ok.

**To Reproduce**
Steps to reproduce the behavior:
1. create aligned timeseries root.o308.pd.IT0001(D001 TEXT encoding=PLAIN, D003 FLOAT encoding=GORILLA)
2. Modify the MQTTClient class in the example module of the source code, the code like this:
> String payload =
String.format(
"{\n"
+ "\"device\":\"**root.o308.pd.IT0001**\",\n"
+ "\"timestamp\":%d,\n"
+ "\"measurements\":[\"**D003**\"],\n"
+ "\"values\":[%f]\n"
+ "}",
System.currentTimeMillis(), random.nextDouble());
Thread.sleep(1);
connection.publish("**root.o308.pd.IT0001.D003**", payload.getBytes(), QoS.AT_LEAST_ONCE, false);
4. run the main method,The execution is successful, no error is reported。
5. no data is written.
6. When I change the device in the code to root.o308.pd.IT0002 (a time series that was not pre-created), it can be written normally.And when i pre-created the unaligned timeseries(create timeseries root.sg.d4.s1 FLOAT encoding=RLE),it also written normally.

> IoTDB> select D003 from root.o308.pd.IT0001;
+----+------------------------+
|Time|root.o308.pd.IT0001.D003|

Empty set.

调研方向

从 example 模块中的 MQTTClient 类开始,使用对齐时间序列 root.o308.pd.IT0001 和测量值 D003 重现该报告。将 MQTT 写入与正常工作的未对齐和新创建案例进行比较,然后使用所示的 SELECT 查询验证 D003 数据已存储到对齐序列中。
