Write idempotent code.Writing idempotent code for your functions ensures that duplicate events are handled the same way. Your code should properly validate events and gracefully handle duplicate events. For more information, seeHow do I make my Lambda function idempotent?. ...
We’ll show how to handle all of these errors in the next sections. Tip The first thing to note when you get a Unicode error is the exact type of the exception. Is it a UnicodeEncodeError, a UnicodeDecodeError, or some other error (e.g., SyntaxError) that mentions an encoding problem?
