The logs endpoint shows any debug logs produced by executed Functions. To have logs show up on this endpoint, add
_10console.log("This is an info level log message from my function")_10_10console.warn("This is a warning log message from my function")_10_10console.error("This is an error log message from my function")
to your Function code and invoke it. The log line will show up at the /Logs sub-resource of an Environment. Only Environments with a deployed build will generate logs.
The Serverless Toolkit has debug log tail ability built in to aid in debugging from the command line. To tail logs for deployed functions, execute the following command from within a deployed Serverless project:
_10twilio serverless:logs --tail
Log lines written at WARN or ERROR level will also show up in the Twilio Debugger. Debugger will store WARN and ERROR logs for up to 30 days. You can set up a webhook to trigger on all (not just Functions) errors and warnings here.
For Functions created via the API, you can show live logs for debugging by loading the Services page in the Twilio Console, opening the Service to track, and clicking the Show Logs toggle in the bottom-right corner of the UI.
The Show Logs toggle will only be visible if you have a live build associated with your environment via a Deployment.
