Schema(Avro) config question

Hey there,

i will need some support on this.

Running connect in standalone mode and mysql-sink with worker.properties like this:

bootstrap.servers=some.url:9093
security.protocol=SSL
ssl.protocol=TLSv1.2
ssl.truststore.location=/opt/kafka/ssl/myTruststore1.jks
ssl.truststore.password=xxx
ssl.keystore.location=ssl/myKeystore.jks
ssl.keystore.password=xxx
ssl.key.password=xxx
value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=https://schema-reg.some.url/subjects/versions/latest/schema
key.converter=io.confluent.connect.avro.AvroConverter
key.converter.schema.registry.url=https://schema-reg.some.url/subjects/versions/latest/schema
key.converter.schemas.enable=true
value.converter.schemas.enable=true
offset.storage.file.filename=/tmp/connect.offsets
plugin.path=/usr/local/share/java,/usr/local/share/kafka/plugins,/opt/connectors,

If i start kafka connect worker with mysql-sink i will not be able to receive data or write data into db:

And if i try to test in console-consumer, i will be able to receive data but like this:

What could be wrong with my avro settings here?

Happy Holidays to everyone

Best
