Parsing JSON with Square Bracket as first character

[MarcDussault]

Hi all,

Looking for help on following issue. I have a JSON returned from a webhook. It parses fine UNTIL I hit a node where the first character is '['. Then it seems Flow interprets it as a string. I converted to JSON (it worked), but no schema is ever correct - even when I use the output from the parse JSON with schema as {} to get raw values.

The issue is that I cannot seem to be able to access the value beneath the square brackets with the [0] signifier. See example below - it goes on for a few thousand lines so I cut it short. Basically, in this example, I am looking to extract the value 'Amina' from the object with name:163716646292718. Ideally with some mapping between them. Then I would repeat this process for all other relevant values. 

[
  {
    "type": "header",
    "label": "Prénom(s), Nom(s), sexe et date de naissance",
    "position_width": "0",
    "condition_formitem_id": "0",
    "condition_operator": "IS_EMPTY",
    "value": ""
  },
  {
    "type": "text",
    "required": true,
    "label": "Prénom(s) tel qu'il apparait sur votre passeport",
    "placeholder": "Prénom(s) tel qu'il apparait sur votre passeport",
    "className": "form-control",
    "name": "163716646292718",
    "subtype": "text",
    "position_width": "1",
    "condition_formitem_id": "0",
    "condition_operator": "IS_EMPTY",
    "userData": [
      "Amina"
    ],
    "value": "Amina"
  },

Using the Parse JSON] action is a convenience and is optional.  You don't need to use Parse JSON.  Here is a link that will get you started with an alternate method of access the data.

@ScottShearer Thanks for the reply. 

I can access some parts of the data no problem using the notation described in the link - see for example these two actions part of the same flow which run fine on parent nodes of the one I am trying to access.

My issue is that the JSON that starts with an array, i.e. square brackets - doesn't seem to work. I would have anticipated the following to simply return the first item in the array - but the Compose action simply fails.
