Kudu lookup join fails with String literal in WHERE clause

When performing a (processing time) temporal table join with a Kudu table, and using a String literal in the WHERE condition:

SELECT d.sensor_id, k.sensor_type, d.`value`
FROM datagen AS d
JOIN `kudu`.`default_database`.`default.sensors` FOR SYSTEM_TIME AS OF d.proctime as k
ON k.sensor_id = d.sensor_id
WHERE sensor_type = 'pressure';

We get the following error:
Caused by: java.lang.ClassCastException: org.apache.flink.table.data.binary.BinaryStringData cannot be cast to java.lang.String at org.apache.flink.connectors.kudu.connector.KuduFilterInfo.predicateComparator(KuduFilterInfo.java:68)
This is because in KuduFilterInfo it tries to cast the literal, which is a BinaryStringData, to a String.
