How to parse multiple json files with nested json arrays in it

[niravhjoshi (Nirav)]

Hi there,
I am trying to parse bunch of json files using logstash.
Following is my logstash conf file

 input
    {
    file
    {codec => multiline
    {
                pattern => '^\{'
                negate => true
                what => previous
    }
    path => '/LogsData/*.json'
    start_position => "beginning"
    sincedb_path => "/dev/null"
    }
    }

    output {
        elasticsearch {
              hosts => ["elasticsearch:9200"]
              manage_template => false
              index => "slinvoice-%{+YYYY.MM.dd}"
                       }
        stdout { codec => rubydebug }
      }

and my json files have array in beginning and followed by 8 level sub components in it.

[
  {
    "associatedInvoiceItemId": "",
    "billingItem": {
      "cancellationDate": "",
      "provisionTransaction": {
        "guestId": "",
        "hardwareId": 805645
      }
    },
    "billingItemId": 131730629,
    "categoryCode": "server",
    "createDate": "2017-08-01T06:26:32-06:00",

    "productItemId": 4578,
    "recurringAfterTaxAmount": "93.84",
    "recurringFee": "93.84",
    "recurringFeeTaxRate": "0",
    "recurringTaxAmount": "0",
    "resourceTableId": 805645,
    "serviceProviderId": 1,
    "setupAfterTaxAmount": "0",
    "setupFee": "0",
    "setupFeeTaxRate": "0",
    "setupTaxAmount": "0",
    "totalOneTimeAmount": 0,
    "totalRecurringAmount": 414.29
  },
  {
    "associatedInvoiceItemId": "",
    "billingItem": {
      "cancellationDate": "",
      "provisionTransaction": {
        "guestId": "",
        "hardwareId": 1234534
      }
    }]

When i start my docker container i am unable to see any json files are getting parse.
