The auto.register.schemas option for a JSON schema registry group in event hub does not seem to work.
Using sample json producer project for azure-schema-registry-for-kafka, I expect a validation error (or some type of error) if I set auto.register.schemas property to false and change the schema of the data I'm sending. Instead it will create a new version of my schema with my updates.
I can reproduce this in the Schema Registry JSON Producer sample project referenced in Azure Event Hub documentation sample project example by changing the CustomerInvoice class.
I have verified this setting works in the Avro Schema Registry. Both tests were done with the kafka client.
