Upsert issue

[Zako-idt]

Hey, my current problem is in configuration, I want to achieve upsert, for example whenever I post this object from kafka topic :

key => "test",
value => {
"FirstName": "Name",
"id": 5,
"TransactionId": "transactionId",
"LastName": "lastName",
"PayInMethod": "visa"
} and then

key => "test",
value => {
"FirstName": "Name",
"id": 5,
"TransactionId": "transactionId",
"PayInMethod": "visa2"
}

I want to get in opensearch object like this : {
"FirstName": "Name",
"id": 5,
"LastName": "lastName",
"TransactionId": "transactionId",
"PayInMethod": "visa2"
}, I have configurations like this :

{
"name": "opensearch-sink-connector",
"connector.class": "io.aiven.kafka.connect.opensearch.OpensearchSinkConnector",
"tasks.max": "1",
"topics": "search-transactions",
"connection.url": "http://opensearch:9200",
"opensearch.index": "search-transactions",
"value.converter": "org.apache.kafka.connect.json.JsonConverter",
"value.converter.schemas.enable": "false",
"opensearch.update.method": "partial", // Enables partial updates and upsert behavior
"opensearch.id.field": "TransactionId", // Use TransactionId as the document ID
"aiven.api_key": "your_aiven_api_key",
"aiven.project": "your_aiven_project",
"aiven.service": "your_aiven_service",
"behavior.on.version.conflict": "ignore"
}

Where is the issue guys, can you help me?
