Lambda Request Processor

A Lambda function that processes user requests and generates structured logs with automatic context enrichment.

Capabilities

Processes incoming requests

• The function accepts an event with a "userId" and "action" field and returns a success response with both values echoed back. @test
• When the event is missing the "userId" field, the function raises a ValueError with message "userId is required". @test

Logs request processing with Lambda context

• The logger automatically captures Lambda function name, request ID, memory limit, and cold start status without explicit code. @test
• The logger includes the userId from the event in all log statements as a persistent context key. @test
