sst start

uses websocket API to send data between the real Lambda and ur local. Websocket API has a 32KB message limit. So behind the scene, if the response is > 32kb, SST uploads the response to S3, and the Lambda function downloads it.

My gut feeling is that uploading the 150KB response to S3 took too long.

That said, uploading a 150KB file to S3 should be really quick… it’d help if we can look at the debug log

Just to sum it up for folks who come across this, make sure to update SST to the latest version 💡
