Invalid S3 request when creating Iceberg tables in Athena

I'm having trouble creating iceberg tables in Athena. I keep getting "Invalid S3 request" as an error message.

CREATE TABLE iceberg_test (
    event_date timestamp, 
    log string
)
PARTITIONED BY ( 
    hour(event_date)
)
LOCATION
    's3://bucket/iceberg/test'
TBLPROPERTIES (
    'table_type'='ICEBERG'
);
