1. In version 1.6, the configuration for schema registry username and password has been moved to where schema.registry is configured.

2. Update the configuration as follows:

Before:

create table answers_to_life with (
  connector='kafka',
  properties.bootstrap.server='localhost:9092',
  properties.sasl.username='xyz',
  properties.sasl.password='123',
  topic='all-answers',
  schema.registry.username='foo',
  schema.registry.password='bar',
) FORMAT DEBEZIUM ENCODE AVRO (
   schema.registry = '<https://schemaregistry>',
);```

After:
```sql
create table answers_to_life with (
  connector='kafka',
  properties.bootstrap.server='localhost:9092',
  properties.sasl.username='xyz',
  properties.sasl.password='123',
  topic='all-answers',
) FORMAT DEBEZIUM ENCODE AVRO (
   schema.registry = '<https://schemaregistry>',
   schema.registry.username='foo',
   schema.registry.password='bar'
);```
