Cassandra UDT not being persisted in cassandra database

Describe the bug

The code converts Json object in request payload to string for UDT. We debugged and found the issue with Cassandra.prototype.create function in loopback-connector-cassandra/lib/cassandra.js. Please provide the solution for the issue.

Logs

Payload object:
{
  id: 'c',
  name: 'otlsgy4',
  phone: '88774622572',
  address: {
    street: 'Sahastradhara Road',
    city: 'Dehradun',
    state_or_province: 'Uttarakhand',
    postal_code: '248001',
    country: 'India'
  }
}


Insert Query by loopback:
INSERT INTO "hotels"("id","name","phone","address") VALUES(?,?,?,?) [
  'c',
  'otlsgy4',
  '88774622572',
  '{"street":"Sahastradhara Road","city":"Dehradun","state_or_province":"Uttarakhand","postal_code":"248001","country":"India"}'
]

Expected Result: 
INSERT INTO "hotels"("id","name","phone","address") VALUES(?,?,?,?) [
  'c',
  'otlsgy4',
  '88774622572',
  {"street":"Sahastradhara Road","city":"Dehradun","state_or_province":"Uttarakhand","postal_code":"248001","country":"India"}
]

Inizia in loopback-connector-cassandra/lib/cassandra.js, in Cassandra.prototype.create, e riproduci il problema usando l’esempio cassandrademo collegato. Traccia come viene associato l’UDT address nei parametri di INSERT; il lavoro è completato quando l’UDT viene persistito come dati strutturati Cassandra invece che come stringa JSON.
