You as a sysadmin know that for sure – Lambda errors, s3 errors or timeout errors.
Your AWS sometimes drives you crazy.
Lambda generates a JSON representation of the error, when your code causes an error. This error document occurs in the invocation log. For synchronous invocations, the document appears in the output.
{
"errorType": "ReferenceError",
"errorMessage": "x is not defined",
"trace": [
"ReferenceError: x is not defined",
" at Runtime.exports.handler (/var/task/index.js:2:3)",
" at Runtime.handleOnce (/var/runtime/Runtime.js:63:25)",
" at process._tickCallback (internal/process/next_tick.js:68:7)"
]
}

If your Lambda function triggers an exception, AWS Lambda recognizes the failure and serializes the exception information into JSON and returns it.
{
"errorMessage": "I failed!",
"stackTrace": [
[
"/var/task/lambda_function.py",
3,
"my_always_fails_handler",
"raise Exception('I failed!')"
]
],
"errorType": "Exception"

When an exception arises in your Lambda function, Lambda will report the exception information back to you. These exceptions can occur in two different places:
The serialized exception information is returned as the payload as a modeled JSON object and given out to CloudWatch logs.
In the initializaion phase, exceptions can be thrown for invalid handler strings, a rule-breaking type or method, or any other validation method. These exceptions are of type LambdaExcpetion.
{
"errorType": "LambdaException",
"errorMessage": "Invalid lambda function handler: 'http://this.is.not.a.valid.handler/'.
The valid format is 'ASSEMBLY::TYPE::METHOD'."
