Http Sink Connector - encounter org.apache.kafka.connect.errors.ConnectException: Unknown value type: java.util.HashMap

[KevinMeng4662]

hi Team,

There is one exception during applying the io.lenses.streamreactor.connect.http.sink.HttpSinkConnector.
Could you help to check that?

Below is connector configuration:

`name=lenseshttp
connector.class=io.lenses.streamreactor.connect.http.sink.HttpSinkConnector
tasks.max=1
topics=topic.name
connect.http.authentication.type=none
connect.http.method=POST
connect.http.endpoint=https://XXXXXXX
connect.http.request.headers="Content-Type:application/cloudevents+json"
connect.http.request.content="{{value}}"
connect.http.batch.count=1

use the kafka converters that better suit your needs, these are just defaults:

key.converter=org.apache.kafka.connect.storage.StringConverter
key.converter.schemas.enable=false
value.converter=org.apache.kafka.connect.json.JsonConverter
value.converter.schemas.enable=false`

Exception:
