+### Loading Data with Kafka Connect Single Message Transforms
+
+For example, consider data in the following format:
+```shell
+{
+  "registertime": 1513885135404,
+  "userid": "User_9",
+  "regionid": "Region_3",
+  "gender": "MALE"
+}
+```
+If we want to add a hard-coded column that doesn't exist in the Kafka topic data, we can use InsertField to accomplish this. Additionally, if we need to convert a bigint timestamp to a formatted time string, we can use TimestampConverter.
+
+```shell
+curl -i http://127.0.0.1:8083/connectors -H "Content-Type: application/json" -X POST -d '{
+  "name": "insert_field_tranform",

 **1. The following error occurs when reading Json type data:**

+### Loading Data with Kafka Connect Single Message Transforms
+
+For example, consider data in the following format:
+```shell
+{
+  "registertime": 1513885135404,
+  "userid": "User_9",
+  "regionid": "Region_3",
+  "gender": "MALE"
+}
+```
+If we want to add a hard-coded column that doesn't exist in the Kafka topic data, we can use InsertField to accomplish this. Additionally, if we need to convert a bigint timestamp to a formatted time string, we can use TimestampConverter.
+
+```shell
+curl -i http://127.0.0.1:8083/connectors -H "Content-Type: application/json" -X POST -d '{
