Can you increase the logging level to debug?

[srini...@gmail.com]

version: Knative 0.16.0 

dont know how to enable debug mode in kafkasource

but i see the consumer group connection to the brokers are established.

Trying following the second step here to enable debug mode: https://knative.dev/docs/eventing/samples/kafka/source/#verify
Also, please make sure to delete the kafka source deployment after updating the configmap, kafkasource controller will automatically bring it up.  

[srini...@gmail.com]

configmap is already in debug mode. and i have deleted the kafksource and redeployed the kafkasource (kind: KafkaSource)

still dont see anything in the log. and seeing the same error

{"level":"info","ts":"2020-","caller":"logging/config.go:110","msg":"Successfully created the logger."}

{"level":"info","ts":"2020-","caller":"logging/config.go:111","msg":"Logging level set to debug"}
