Unable to display JSON records with null values

[Sid]

Hello experts,

I have a JSON data like below:

[
  {
    "123": {
      "Party1": {
        "FIRSTNAMEBEN": "ABC",
        "ALIASBEN": "",
        "RELATIONSHIPTYPE": "ABC, FGHIJK LMN",
        "DATEOFBIRTH": "7/Oct/1969"
      },
      "Party2": {
        "FIRSTNAMEBEN": "ABCC",
        "ALIASBEN": "",
        "RELATIONSHIPTYPE": "ABC, FGHIJK LMN",
        "DATEOFBIRTH": "7/Oct/1969"
      }
    },
    "GeneratedTime": "2022-01-30 03:09:26"
  },
  {
    "456": {
      "Party1": {
        "FIRSTNAMEBEN": "ABCD",
        "ALIASBEN": "",
        "RELATIONSHIPTYPE": "ABC, FGHIJK LMN",
        "DATEOFBIRTH": "7/Oct/1969"
      },
      "Party2": {
        "FIRSTNAMEBEN": "ABCDD",
        "ALIASBEN": "",
        "RELATIONSHIPTYPE": "ABC, FGHIJK LMN",
        "DATEOFBIRTH": "7/Oct/1969"
      },
      "Party3": {
        "FIRSTNAMEBEN": "ABCDDE",
        "ALIASBEN": "",
        "RELATIONSHIPTYPE": "ABC, FGHIJK LMN",
        "DATEOFBIRTH": "7/Oct/1969"
      }
    },
    "GeneratedTime": "2022-01-30 03:09:26"
  },
  {
    "345": {


    },
    "GeneratedTime": "2022-01-30 03:09:26"
  }
]

However, when I try to display this JSON using below code, it doesn't show
the blank records. In my case I don't get any records for 345 since it is
null but I want to display it in the final flattened dataset.

val df = spark.read.option("multiline",
true).json("/home/siddhesh/Documents/nested_json.json")

Spark version:3.1.1

Thanks,
Sid
