Unable to save array entry for list<text> column

[tejashande]

I am using Cassandra datasource in loopback 3, and trying to store values in list datatype column of a table(keyspace) of Cassandra datasource. But while creating an entry from loopback explorer, we are getting TypeError: Not a valid list value, expected Array obtained '["Morning","Afternoon","Evening"]'

Here is my loopback model:

{
  "name": "Time",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "options": {
      "type": "array",
      "format": "list"
    }
  },
  "validations": [],
  "acls": [],
  "methods": {}
}

Tried debugging loopback-cassandra-datasource and saw options converted to string in params.

Data passed from loopback explorer:

{
  "options": ["Morning","Afternoon","Evening"]
}

Data logged from beforeRemote hook of the model:

{ options:
   [ 'Morning',
     'Afternoon',
     'Evening' ]
}

package.json

"dependencies": {
  "loopback": "3.26.0",
  "loopback-boot": "2.28.0",
  "loopback-component-explorer": "6.4.0"
  "loopback-connector-cassandra": "1.7.1"
}

The typeof options is object. I was debugging loopback cassandra connector and found typeof options as string in encoder.js of cassandra-driver node module. We have migrated from MongoDB to Cassandra and didn't face any issues for MongoDB driver. To what type or which format do I need to set for options property? Please let me know if any additional information required. Thank you in advance.
