How to insert map of maps data in cassandra unit?

Question

I'm trying to insert some dummy data in cassandra unit table which has a new map of maps field frozen<map<timestamp, frozen<map<text, double>>>>. The problem is the data load query I have works on actual Cassandra DB but throws following error on Cassandra unit cluster created during unit tests execution.

com.datastax.driver.core.exceptions.InvalidQueryException: Invalid user type literal for cass_unit_test_table of type frozen<map<timestamp, frozen<map<text, double>>>>

Table Structure

CREATE TABLE cass_unit_test_table (
  id double,
  receivingsum double,
  qtyOne frozen<map<text, double>>,
  qtyTwo frozen<map<timestamp, frozen<map<text, double>>>>,
  PRIMARY KEY ((id),sum)
)

Insert query if inserting directly into DB

insert
    into
        cass_unit_test_table(
            id,
            receivingsum,
            qtyOne,
            qtyTwo
        )
    values(
        0,
        0,
        {'promo': 4,'order': 5, 'xyz': 6 },
        {1648166400000:{'foo':0.0,'bar':0.0 }}
    );
