Hi, I have set up the connector with the following configuration :

apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaConnector
metadata:
  name: my-source-connector
  namespace: kafka
  labels:
    strimzi.io/cluster: my-connect-cluster
spec:
  class: io.aiven.kafka.connect.opensearch.OpensearchSinkConnector
  tasksMax: 10
  config:
    name: my-source-connector
    topics: os-topic
    connection.url: http://MY_OC_INGEST_URL:9200  
    connection.username: *****
    connection.password: *******
    value.converter: org.apache.kafka.connect.json.JsonConverter
    key.converter: org.apache.kafka.connect.storage.StringConverter
    tasks.max: 1
    schema.ignore: true
    key.ignore: true
    value.converter.schemas.enable: false 

but I get this error in all tesks :

this issue was because opensearch is configured to use https for 9200 by default so connector failed to connect using http but I still have issue as now opensearch have privet certificate and the connector can't verify the certificate so it fails

[muralibasani]

Can you try with setting in the config ssl_certificate_verification: false

[yoyoraso]

hello @muralibasani it still the same, I don't think ssl_certificate_verification is a vaild attribute in configration as I don't see it handled in the code
