Could use a hand troubleshooting this branching logic issue in CXone Studio. I am integrating a lightweight Genesys Cloud status widget built with SvelteKit, but I need to handle some pre-routing logic in the CXone script before transferring the call. The goal is to check an external API response via a GetRESTProxy action and then branch based on the status field returned in the JSON payload.
I have configured the GetRESTProxy to call my internal endpoint. The response body is valid JSON: {"status": "available", "queueId": "123"}. I then use an ASSIGN action to parse this JSON and extract the status into a variable named apiStatus. The assignment expression is jsonPath(responseBody, '$.status').
Next, I have an IF action that checks apiStatus == 'available'. If true, it should transfer to a specific queue. If false, it should play an IVR message. However, the logic always falls through to the ‘false’ branch, even when the API returns ‘available’. I have verified the GetRESTProxy output using the debug logs, and the responseBody variable contains the correct JSON string.
The issue seems to be with how the ASSIGN action handles the JSON path evaluation or how the IF action compares the string. I suspect there might be a type mismatch or a whitespace issue in the extracted value. I have tried trimming the result using trim(jsonPath(responseBody, '$.status')) in the ASSIGN action, but it still fails.
Is there a specific syntax for comparing strings in CXone Studio IF actions? Or is the jsonPath function returning a different data type than expected? I need this to work reliably for my dashboard integration. Any insights on debugging Studio variable assignments would be appreciated.
You need to ensure the JSON path in your Studio condition uses the correct syntax for accessing nested objects. The standard expression evaluator requires explicit dot notation or bracket syntax depending on the key names. If your response payload is {"data": {"status": "active"}}, your condition should evaluate body.data.status.
The SDK doesn’t help here since this is pure Studio logic, but debugging the payload structure is critical. I often use a simple Python script to mock the API response and print the JSON path before wiring it into Studio. This avoids the trial-and-error of redeploying the flow.
Make sure the GetRESTProxy action is configured to return the full JSON body, not just a status code. If the path is invalid, Studio defaults to false or null, causing unexpected branching. Check the raw response in the interaction logs to confirm the structure matches your expression.
I typically get around this by validating the JSON path against the raw payload returned by the GetRESTProxy action. The suggestion above is correct regarding body.data.status, but Studio expressions often fail if the JSON structure includes an outer envelope or if the field names contain special characters. I recommend adding a temporary SetVariable action immediately after the REST call to store the raw response body. Then use a debug log or a simple redirect to inspect the exact variable content, ensuring you are targeting the correct nesting level like body.data.status rather than assuming a flat structure.
For Zapier custom triggers, I often parse the webhook payload using the JSON.parse() method in the CLI to ensure the data types match expectations before mapping them to the output schema. In Studio, the expression evaluator is strict about null values, so wrapping the path evaluation in a isNotEmpty() check prevents runtime errors when the external API returns an empty or malformed response. This approach avoids silent failures that are hard to trace in the CXone logs.
If I remember correctly, the null wrapUpCode issue stems from querying conversations that are still in progress. The analytics data export only populates that field after the conversation is fully closed and processed. Use the filter above to ensure you only retrieve closed records, which avoids the stale nulls I often see in my Glue jobs.
This seems like a classic case where the studio expression engine chokes on nested json without explicit type casting. the suggestion above about checking body.data.status is correct in theory, but often fails if the rest proxy returns a string instead of a parsed object. i usually bypass this by caching the raw response in redis with a short ttl to inspect the actual structure.
try adding a setvariable action to cast the body explicitly:
then check status_val in your if condition. this avoids the dot notation ambiguity. also ensure your redis key includes the conversation id for traceability. if you still get null, log the raw rest_response.body to a file or external endpoint. often the api wraps the result in an additional envelope not shown in docs. debugging the actual payload is faster than guessing studio syntax.
