'Cassandra Spring No Converter Found Capable of Converting from Type Instant to type Long

Am getting a No converter found capable of converting from type Instant to type Long while using Spring and Cassandra.

I have 2 Instant fields writtenDate (in the object primary key) and hotelAddedDate in the object. However, I do not have any Long fields; thus, I am a little confused.

Does anyone have an idea how to fix this error?

In CustomerReviewsByHotelAndLastNameAndFirstName.java:

...

@Column("hotel_added_date")
@CassandraType(type = CassandraType.Name.TIMESTAMP)
