First things first, log into the Xano platform and head over to your workspace dashboard. This is your command center for managing API collections, database tables, and all the other cool stuff.

On the left-hand sidebar, you'll see an "API" option. Click on that to get to your collections. Pick the specific API collection you want to debug or log errors for.

Inside your chosen API collection, find the endpoint you want to debug. Click the "Edit" button to tweak the endpoint settings. Look for the "Debug Mode" toggle and switch it on. This will give you detailed logs for that endpoint.

Once Debug Mode is on, trigger the endpoint by making a request via the "Run & Debug" tab. After the endpoint runs, you'll see logs that break down the execution process step-by-step, including input and output parameters, any errors, and extra debug info.

For more specific logging, you can add custom log messages. In the endpoint editor, drag and drop the "Debug" function node into your workflow. Configure the Debug node to log specific values or messages you want to keep an eye on. These logs will show up in the execution logs once the endpoint runs.

To handle and log errors efficiently, use "Try/Catch" nodes in your workflow. The "Try" node will wrap the code that might throw an error, and the "Catch" node will handle any errors that pop up. Inside the "Catch" node, you can set up logging functions to capture error details.

Go to the "History" tab within your API collection to see past execution logs. This tab gives you historical data for endpoint executions, including any errors and debug messages logged during those runs.

Make sure your API endpoints return meaningful error responses. Customize error responses by setting up conditional statements in your endpoint workflow. Use the "Response" node to configure different error messages and HTTP status codes, making it easier to diagnose issues based on client-side error reports.

Test the endpoint thoroughly under different scenarios to validate that logging and error handling are working as expected. Use both successful and erroneous input data to ensure comprehensive coverage.

By following these steps, you can efficiently debug and log errors in Xano, ensuring a more robust and reliable API.
