Trying to configure the GetExternalContactAction to look up a customer by phone number. Console handles the initial trigger fine, but the external lookup keeps spitting out a blank JSON object. Endpoint configuration targets /api/custom/lookup with the caller ID passed through the phone variable. Server logs confirm a solid 200 response carrying the full account JSON. Field mapping stays empty anyway. Tried these steps: switched HTTP method to GET, bumped timeout to fifteen seconds, wrapped response in a data key. None of it worked. Debug output shows the action completes without throwing errors. Output just reads {}. It’s probably a schema mismatch. We’ve followed documentation examples to the letter, but the field mapping fails every single time. Calls still drop into the default queue without pulling the account balance.
