WARNING

import { Logger } from '@aws-lambda-powertools/logger';
import { LogLayer } from 'loglayer';
import { PowertoolsTransport } from '@loglayer/transport-aws-lambda-powertools';

// Create a new Powertools logger instance
const powertoolsLogger = new Logger({
  serviceName: 'my-service',
  logLevel: 'INFO'
});

// Create LogLayer instance with Powertools transport
const log = new LogLayer({
  transport: new PowertoolsTransport({
    logger: powertoolsLogger
  })
});

// Use LogLayer as normal
log.withMetadata({ customField: 'value' }).info('Hello from Lambda!');
