	function getLambdaEventSource(event) {
	if (event.Records && event.Records[0].cf) return 'isCloudfront';

	if (event.configRuleId && event.configRuleName && event.configRuleArn) return 'isAwsConfig';

	if (event.Records && (event.Records[0].eventSource === 'aws:codecommit')) return 'isCodeCommit';

	if (event.authorizationToken === "incoming-client-token") return 'isApiGatewayAuthorizer';

	if (event.StackId && event.RequestType && event.ResourceType) return 'isCloudFormation';
