Specifying producer.value.serializer in configurationOverrides doesn't seem to be reflected to actual option

[neolunar7]

Hi, while using Kafka Connect, I'm using the helm values.yaml as below. However, all of these configurationOverrides cause WARN of WARN The configuration ... was supplied but isn't a known config. Referring to other issues this WARN seems to be fine. However, the other issue is that looking at INFO ProducerConfig values and INFO ConsumerConfig values, the options I specified in configurationOverrides in helm values.yaml seems not to be reflected. I tried both producer.value.serializer and value.serializer, but looking at INFO ProducerConfig values, they were not reflected.

This is really confusing, and any help would be greatful.

...
configurationOverrides:

  "value.converter": "org.apache.kafka.connect.json.JsonConverter"
