Console.log output not appearing – AWS SAM Node.js

Hi everyone,

I ran into a bit of an interesting issue today after updating AWS SAM. All of my node log output stopped appearing in my console locally.

For now, there’s a pretty simple workaround:

sam build --use-container && sam local start-api 2>&1 | tr "\r" "\n"

Append 2>&1 | tr “\r” “\n” (including quotes) to your start-api command and you should begin to see the output as expected:
