How can I handle errors in Ruby Lambda functions?

You can handle errors in Ruby Lambda functions using begin-rescue blocks. This allows you to catch exceptions and manage them gracefully.

Can you give me an example of using begin-rescue?

Sure! Here's a simple example:

begin
  # Your code here
rescue StandardError => e
  puts "Error occurred: \\#{e.message}"
end

What if I want to log the error instead of just printing it?

You can use a logging library like Logger. Just replace the puts statement with a log method, like this:

require 'logger'
logger = Logger.new(STDOUT)

begin
  # Your code here
rescue StandardError => e
  logger.error("Error occurred: \\#{e.message}")
end

Is there a way to re-raise the error after logging it?

Yes, you can re-raise the error by adding raise after logging it. Here's how:

begin
  # Your code here
rescue StandardError => e
  logger.error("Error occurred: \\#{e.message}")
  raise
end
