A Python automation job posts an update to SD-WAN Manager and fails, but the script prints only 'HTTP 400' while the same request works from Postman. The engineer needs to know exactly which part of the request was rejected. Which part of the error response should the script log first to identify the failing input?
Select an answer to reveal the explanation.
Short Explanation
Log the response body first—it may spell out which input was rejected, like a note explaining what went wrong rather than just a red flag. The status code tells you the request failed, but not which value caused it, and error details may be structured differently.
Full Explanation
A 4xx response indicates a client-side error category, but the status code alone does not identify the rejected input. Inspect the response body for any message or details the server provides; the format and specificity can vary, and the body is not guaranteed to name a field. Switching to a GET request probes the path rather than the rejected POST input. Re-authenticating does not address the request content; authentication issues are generally indicated by 401 or 403 responses, not by a 400 status. Searching the manager event log is a less direct way to investigate, and it may not provide field-level detail. Practical check: examine the body returned for the failed call and log its available error details, including any nested structure.
