Stuck on some basic branching logic inside a CXone Studio Snippet. The goal is simple: check a custom attribute, set a flow variable, and branch based on that value. It’s not working as expected. The IF condition evaluates, but the ASSIGN action inside the true block doesn’t seem to persist to the flow level, or maybe I’m missing a scope keyword.
Here’s the snippet code:
VAR localResult = "default"
IF (flow.customer.tier == "vip") {
ASSIGN localResult = "vip_path"
} ELSE {
ASSIGN localResult = "standard_path"
}
RETURN localResult
The snippet returns the correct string when I debug it in isolation. But when I call this snippet from the main flow, the flow variable I’m trying to set (let’s say flow.routing.target) never updates. I’ve tried using flow.routing.target = localResult directly in the ASSIGN, but Studio throws a compile error saying “Cannot assign to read-only property” or something similar.
Is there a specific way to declare flow-level variables in a snippet so they can be written to? Or do I need to return the value and map it in the calling flow’s ASSIGN step? The documentation on variable scope in snippets is pretty sparse. Just looking for the correct syntax to pass a value out of the snippet into the main flow context without hitting scope walls.
Also, is there a performance hit if I do multiple IF/ELSE chains inside a snippet versus handling the logic in the flow builder visually? We’ve got a complex decision tree and the canvas is getting messy, so I’d prefer to push as much logic into snippets as possible. Any tips on structuring the ASSIGN calls to avoid those read-only errors would be appreciated.
Currently getting a runtime warning that says “Variable scope mismatch” when the flow tries to use the returned value. Not sure if that’s just noise or if it’s breaking the assignment.
Appreciate any pointers on the correct pattern for this.
