I also the same issue. I was setup kafka with kraft and I want to config SASL_PLAIN with SCRAM-SHA-512 for controller and broker, but when start it was error "org.apache.kafka.common.errors.SaslAuthenticationException: Authentication failed during authentication due to invalid credentials with SASL mechanism SCRAM-SHA-512"

This is my config:

server.properties

process.roles=broker,controller

node.id=1

broker.id=1

broker.rack=rack1
