Why won't my IoT Core rule to timestream parse the data in a usable way?

Question

So, I have data coming into IoT Core that looks like this.
{
  "clientID": "AWSPGFIFBI",
  "topic": "ie/d/j/simatic/v1/s7c1/dp/r/Test1200/default",
  "protocol": "mqtt",
  "payload": {
    "seq": 367645,
    "vals": [
      {
        "dataType": "",
        "id": "101",
        "name": "",
        "qc": 3,
        "ts": "2023-06-20T16:02:27.4078740Z",
        "val": 54
      }
    ]
  }
}

How would I go about get the nested data in the array to show up in Timestream for example the "val" or "id"?

Thanks

Answer

You can use the nested object queries to get the values. 
[https://docs.aws.amazon.com/iot/latest/developerguide/iot-sql-nested-queries.html]()

In your example , use the below messaging routing rule to get the value of  "id" and "val".

SELECT  get(payload.vals,0).val  AS VAL FROM 'TestRule'

SELECT  get(payload.vals,0).id  AS ID FROM 'TestRule'

I used "TestRule" as source generating the data.
