When sending a GetRecordsRequest to retrieve ML records, the deserialization of the Anomaly object fails due to a missing required property 'byFieldName' in the AnomalyCause class.

Hello, thank you for reporting this! It's an issue in the API specification used to produce the Java code. Once the API specification is fixed, the Java client code will be updated to resolve this issue.
