I’ve just discovered [https://serverless.com/framework/docs/providers/aws/cli-reference/invoke-local/#invoke-local](https://serverless.com/framework/docs/providers/aws/cli-reference/invoke-local/#invoke-local) which should be linked from [https://github.com/serverless/serverless/issues/281](https://github.com/serverless/serverless/issues/281) & their should be a topic called **debug** upon [https://serverless.com/framework/docs/](https://serverless.com/framework/docs/) referring to this.

But frustratingly what local invoking doesn’t do, is stepping through your code and inspect variables etc etc. That to me seems sorely missing. 😭

Furthermore I find that especially once deployed to production, it’s VERY handy to have copies of the input event.json to re-run / re-create / reproduce issues locally in development. Short of developing this functionality everytime I write a lambda function, could there be some trick I am missing?

If you want production to save copies of the input event for each request you can simply log the event to Cloud Watch.

```javascript
console.log("Event", event);

```

Then you can copy the event from Cloud Watch to event.json to test locally.

True, thanks for the tip. Though would be nice if there was some convenience function since copy/pastes can be fiddly.

Btw, what about a “debugging JS” story? 🙂
