Lamdba to pull Cloudfront from AWS Config query

Hi,

I am trying to use a lamdba to pull from multi accounts and grab CloudFront information, but the following aliases "cname" won't come back

selectExpression = "select accountId,resourceId,awsRegion,arn,resourceCreationTime,configurationItemStatus,configuration.domainName,configuration.lastModifiedTime,configuration.distributionConfig.aliases.items,configuration.distributionConfig.origins.items.customOriginConfig.*,configuration.distributionConfig.origins.items.customOriginConfig.httpPort,configuration.distributionConfig.origins.items.customOriginConfig.httpsPort,configuration.distributionConfig.origins.items.customOriginConfig.originSslProtocols,configuration.distributionConfig.origins.items.domainName"
    selectExpression = selectExpression + " where resourceType = 'AWS::CloudFront::Distribution' 

print(result['configuration']['distributionConfig']['aliases']['items']) 

gets an error below but get origin works fine:

print(result['configuration']['distributionConfig']['origins']['items'])

Any suggestions?

also in their docs: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-distributionconfig.html#cfn-cloudfront-distribution-distributionconfig-aliases and works with CLI

Error:
