Converting a record or table object to text and/or a way to access fields within a table/record that are embedded

[rbeste]

Have a Copilot Studio project utilizing the connector to Azure CLU which returns its result as a record object. I just need to the key values out of that record so I can pass it to a Power Automate Flow which only takes text as an input but I can't seem to figure out how to get those key field(s) into a text string. JSON/PARSEJSON don't work on Record/Table objects and TEXT doesn't either. When trying to use CONCAT I can get so far but since the structure of that record is below, how do I get to the key values since referencing them with record.prediction.entities[0].extraInformation[0].key throws an error saying it doesn't like the [0] notation. What am I missing here?
{
"prediction": {
"entities": [
{
"category": "Service",
"confidenceScore": 1,
"extraInformation": [
{
"extraInformationKind": "ListKey",
"key": "value returned 1"
},
{
"extraInformationKind": "ListKey",
"key": "value returned 2"
}
],
"length": 18,
"multipleResolutions": false,
"offset": 0,
"text": "CRM implementation",
"topResolution": {
"resolutionKind": "TextSpan",
"value": "CRM implementation"
}
}
],
"intents": [

I'll need to confirm which Power-Fx version Copilot Studio is running. A recent change introduced support for the Index function with untyped objects.

>> Set(t,ParseJSON("{ ""prediction"": { ""entities""....}")
<Untyped: Use Value, Text, Boolean, or other functions to establish the type>

>> Text( Index( Index( t.prediction.entities, 1).extraInformation, 1).key)
"value returned 1"

Currently Concat does not support untyped objects. A possible way yo achieve your goal is to combine Concat + ForAll:

>> Set(t,ParseJSON("{ ""prediction"": { ""entities""....}")
<Untyped: Use Value, Text, Boolean, or other functions to establish the type>

>> Concat(ForAll(Index(t.prediction.entities,1).extraInformation, Text(ThisRecord.key)), Value, ",")
"value returned 1,value returned 2"

I've tried Concat with ForAll I can't tell you how many iterations and it always comes back to either the field (key) is unknown or Value is seen as a Table and it doesn't like that. After trying everything I could find, I finally got it to work using the following: But there has got to be a better way of simply accessing fields in a table/record object as strings than this...
With(
{
keys: ForAll(
Global.ConversationResult.prediction.entities As en,
Concat(
ForAll(
en.extraInformation As ex,
If(
ex.extraInformationKind = "ListKey",
ex.key,
Blank()
)
),
Value,
", "
)
)
},
Concat(
Split(keys, ", "),
Result,
", "
)
)
