Lambda@Edge - Unable to increase memory size
Hello,
Trusted Advisor gave me a performance recommandation which was to increase the memory size of some of my Lamda@Edge from 128Mo to at least 160Mo.
So I proceeded to the update using Cloudformation but the deploy failed:
I guess the under-provisioned memory side for functions check should be reviewed in order to ignore memory size increase for lambdas attached to Cloudfront; or, Lambda@Edge could accept memory size limit above 128Mo
Did anyone else encounter this same problem ?
Thank you in advance,

For Lambda functions triggered by View request or Viewer response event, memory is capped at 128MB. Can you verify that?
Lambda@Edge has a number of limitations, one of which is a maximum of 128MB memory size for viewer request and viewer response events. This does not apply to origin request and origin response events.
You can find this limit and others here https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cloudfront-limits.html#limits-lambda-at-edge

Yes, it is (as Cloudformation deploy error shows). Knowing this limitation, I don't know why AWS Trusted Advisor recommends me to increase it to 160MB
Could be the case that Trusted Advisor only considers computation metrics
