Data Action failing with 500 on Cognigy profile query - JSON parse error?

Architect & Flows
1

Trying to fetch a customer file from NICE Cognigy via a Genesys Cloud Data Action in Architect. The endpoint works fine in Postman, but the platform keeps bombing out with a 500 Internal Server Error.

The response from Cognigy is valid JSON, but I suspect the Data Action parser is choking on the structure. Here’s the payload I’m getting back:

{
 "data": {
 "attributes": {
 "firstName": "John",
 "loyaltyTier": "Gold"
 }
 }
}

I have the mapping set to response.data.attributes.firstName, but the logs just say JSON parse error: Unexpected token. I’ve tried wrapping the value in quotes and changing the expected type to string, but no luck.

The request headers include Content-Type: application/json and the auth token is valid. I’ve even added a retry step to rule out transient network issues, but it fails every single time. Is there a specific schema requirement for the outer wrapper that I’m missing? The docs don’t mention anything about nested objects causing parse failures.

I’m stuck. Can someone point me to a working example of parsing nested JSON from an external API in a Data Action?

  • Check if the response content-type header is explicitly application/json. The Data Action parser might be treating it as text.
  • Add a Content-Type: application/json header to your request config in Architect just to be safe.
  • Verify the endpoint isn’t returning extra whitespace or BOM characters that break strict JSON parsing.
