Empty fields in jsonb[] giving exception for a select query

For an array of JsValue when one of the values for a field is empty string, I’m getting Json.parse(_) exception for the select query. Is this related to utils.SimpleArrayUtils.fromString ?

    implicit val playJsonArrayTypeMapper =
      new AdvancedArrayJdbcType[JsValue](pgjson,
        (s) => utils.SimpleArrayUtils.fromString[JsValue](Json.parse(_))(s).orNull,
        (v) => utils.SimpleArrayUtils.mkString[JsValue](_.toString())(v)
      ).to(_.toList)

Example Jsonb[]:

[{
     "id": "1",
     "type": ""
},
{
      "id": "2",
     "type": "GET"
}]

Unexpected character ('}' (code 125)): expected a value

Example:

[{
     "id": "1",
     "type": "",
     "url": "google.com"
}]

Unexpected character (',' (code 40)): expected a value

I think this was a similar issue for string #294.
