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"}
]

Commencez dans loopback-connector-cassandra/lib/cassandra.js, au niveau de Cassandra.prototype.create, et reproduisez le problème à l’aide de l’exemple cassandrademo lié. Suivez la manière dont l’UDT address est lié dans les paramètres de INSERT ; le travail est terminé lorsque l’UDT est persisté en tant que données structurées Cassandra plutôt qu’en tant que chaîne JSON.
