How can I use logging to improve troubleshooting of JSON structure validation errors in GST?

Implement robust logging to record the JSON data being sent to the GST API *before* submission, as well as the API's response (including the error message). Include timestamps, transaction IDs, and any relevant context in the log entries. This helps you track down the source of the error and correlate it with specific transactions. Use appropriate log levels (e.g., debug, info, warning, error) to control the amount of logging output.
