How can I handle errors in AWS SAM templates?

You can handle errors in AWS SAM templates by using the AWS::Serverless::Function resource's Policies and Environment properties.

Can you give me an example of error handling in a SAM template?

Sure! You can define a Lambda function with a dead-letter queue (DLQ) to capture failed events. Here's a sample snippet:

Resources:
  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: index.handler
      Runtime: nodejs14.x
      DeadLetterQueue:
        Type: SQS
        Properties:
          QueueName: MyDLQ

What are some common errors I should be aware of?

Common errors include permission issues, resource limits, and incorrect configurations. Always check CloudWatch logs for details.

How can I debug my SAM template?

You can use the SAM CLI to validate your template with sam validate and deploy it in a local environment using sam local.
