Hello Power Platform Community,

I am encountering an issue in Copilot Studio where I cannot access variables (both global and non-global) from within a For Each loop. Here is the situation:

I have initialized a variable (DealersPayload) outside the loop, either as a global variable or a regular one.
When I try to reference this variable inside the For Each loop to dynamically update its value (e.g., concatenating JSON objects), I get an error indicating that the variable does not exist or is not recognized.

Here’s an example of my setup:

Variable Initialization (outside the loop):
- kind: SetVariable
id: setVariable_DealersPayload
variable: DealersPayload
value: "[]"
Inside the Loop:
- kind: Foreach
id: foreach_Top
items: =Topic.Top5
value: CurrentTopDealer
actions:
- kind: SetVariable
id: setVariable_UpdatePayload
variable: DealersPayload
value: |
JSON(
Concat(
DealersPayload,
"[",
If(
Length(DealersPayload) > 2,
",",
""
),
"{",
"\"Dealer_Code\": \"", Text(CurrentTopDealer.Value), "\",",
"\"Score\": ", Text(CurrentTopDealer.Score), ",",
"\"Category\": \"Top\"",
"}",
"]"
)
)

However, every time I try to use DealersPayload inside the loop, I get an error saying the variable is not recognized. This happens even when I declare DealersPayload as a global variable.

Questions:

Why are variables initialized outside the loop not accessible from within the loop in Copilot Studio?
Is there a specific way to pass or reference variables within a For Each loop?
Are there any known limitations or workarounds for dynamically updating variables during loop iterations?

I would greatly appreciate any insights, workarounds, or guidance on how to resolve this issue.
