Wrong type converter with Avro format

[onepas]

When used connector in ksqldb, some data types ex: DECIMAL, DATE (in ksqldb table) are not correct when convert value
ex:
-1,507,945.00 -> "9wMO/A=="
35,068.00 -> "NYJw"
01 DEC 2023 -> 19692

CREATE SINK CONNECTOR SINK_TRANSACTIONS_RULE01_HTTP WITH (
    'connector.class'                     = 'io.aiven.kafka.connect.http.HttpSinkConnector',
    'http.url'                            = 'https://webhook.site/6d74bf60-f754-4f57-b1ee-8eed9208b9ea',

Same here,

The received body:

{"ORDERID":"Mw==","ORDERDATE":1109721600000,"CUSTOMERID":"ZQ==","AMOUNT":3250.25}]

Both ORDERID and CUSTOMERID are org.apache.kafka.connect.data.Decimal in the avro schema

My configuration:

{
    "name": "http_sink_connector",
    "config": {
        "topics": "PULL_ORDER_DATA",
        "tasks.max": "1",

        "http.url": "http://api:8080/api/orderData",

        "http.authorization.type": "none",

}
