When launching debezium-server via:

java -jar ./debezium-server-dist/target/debezium-server-dist-3.0.0-SNAPSHOT-runner.jar io.debezium.server.Main

it errors out with the log-line:

Failed to load mandatory config value 'debezium.sink.type'. Please check you have a correct Debezium server config in /<redacted>/debezium/debezium-server/conf/application.properties or required properties are defined via system or environment variables.

This is broken in two ways:

• the printed path is wrong. quarkus loads application.properties from the config directory: https://quarkus.io/guides/config-reference
• the error message is logged via println. LOGGER should be used
  instead (otherwise depending on the logging-setup the message might be
  dropped - due to not being json)

Both issues were fixed in the following PR:
