Hello -- Is there a way to load a JSON from a file. I have a "JSON" file which has a sting 1035164 long with the following format: 
[
    {
        "id": "12345",
        "title": "John Smith",
        "image_uri": "https://<some URL>",
        "image_timestamp": "1496781334",
        "image_url":"https://<some URL>",
        "is_restricted_under_18_only": false,
        "is_restricted_adult_only": false
    },
...
    {
        "id": "67890",
        "title": "Mary Jane",
        "image_uri": "https://<some URL>",
        "image_timestamp": "1496781334",
        "image_url": "https://<some URL>",
        "is_restricted_under_18_only": false,
        "is_restricted_adult_only": false
    }
]
There are ~ 4839 entries.  **Is it possible to parse a JSON string by loading a from a file?** I tried this...
  S filename="/tmp/pictures.json"
  S stream=##class(%Stream.FileCharacter).%New()
  S sc=stream.LinkToFile(filename)
  I ('sc) W "Error on linking file "_filename,! W
  try {
    set obj=##class(%DynamicAbstractObject).%FromJSON(stream)
  } catch ex {
    w "Error. Unable to parse file "_filename,!
    w "Error type   "_ex.Name,!
    w "Error code   "_ex.Code,!
    w "Error location "_ex.Location,!
    set obj=""
  }
  q obj
  Q 
... but I get the following error: Error. Unable to parse file /epicdc/data/pictures.json
Error type   <CLASS DOES NOT EXIST>
Error code   150
Error location fromFile+7^XJSON
Thanks!
