Describe the bug

I got the following error:

E3030 You must specify a valid value for CacheNodeType (cache.m7g.xlarge). Valid values are ["cache.c1.xlarge", "cache.m1.large", "cache.m1.medium", "cache.m1.small", "cache.m1.xlarge", "cache.m2.2xlarge", "cache.m2.4xlarge", "cache.m2.xlarge", "cache.m3.2xlarge", "cache.m3.large", "cache.m3.medium", "cache.m3.xlarge", "cache.m4.10xlarge", "cache.m4.2xlarge", "cache.m4.4xlarge", "cache.m4.large", "cache.m4.xlarge", "cache.m5.12xlarge", "cache.m5.24xlarge", "cache.m5.2xlarge", "cache.m5.4xlarge", "cache.m5.large", "cache.m5.xlarge", "cache.m6g.12xlarge", "cache.m6g.16xlarge", "cache.m6g.2xlarge", "cache.m6g.4xlarge", "cache.m6g.8xlarge", "cache.m6g.large", "cache.m6g.xlarge", "cache.r3.2xlarge", "cache.r3.4xlarge", "cache.r3.8xlarge", "cache.r3.large", "cache.r3.xlarge", "cache.r4.16xlarge", "cache.r4.2xlarge", "cache.r4.4xlarge", "cache.r4.8xlarge", "cache.r4.large", "cache.r4.xlarge", "cache.r5.12xlarge", "cache.r5.24xlarge", "cache.r5.2xlarge", "cache.r5.4xlarge", "cache.r5.large", "cache.r5.xlarge", "cache.r6g.12xlarge", "cache.r6g.16xlarge", "cache.r6g.2xlarge", "cache.r6g.4xlarge", "cache.r6g.8xlarge", "cache.r6g.large", "cache.r6g.xlarge", "cache.r6gd.12xlarge", "cache.r6gd.16xlarge", "cache.r6gd.2xlarge", "cache.r6gd.4xlarge", "cache.r6gd.8xlarge", "cache.r6gd.xlarge", "cache.t1.micro", "cache.t2.medium", "cache.t2.micro", "cache.t2.small", "cache.t3.medium", "cache.t3.micro", "cache.t3.small", "cache.t4g.medium", "cache.t4g.micro", "cache.t4g.small"]

However, according to AWS documentation, the latest version are M7G node types: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/CacheNodes.SupportedTypes.html

Expected behavior

I would expect not to have this issue because the linter is not up-to-date with the documentation. It runs without bug on AWS.

Reproduction template

  ElasticacheCluster:
    Type: AWS::ElastiCache::CacheCluster
    Properties:
      Engine: redis
      CacheNodeType: cache.m7g.xlarge

What region are you validating against? We get this data from pricing APIs and this is particular to the region.

Same issue for us. Any updates on this? region us-east-1

[kddejong]

I still can't replicate this. Any chance you have AWS_DEFAULT_REGION or AWS_REGION setup where you are running this?

I'm no longer in the company where I had this issue. However, I remember it was running on eu-west-1.

I am also facing this issue.

E3030 You must specify a valid value for CacheNodeType (cache.r7g.xlarge). Valid values are ["cache.c1.xlarge", "cache.m1.large", "cache.m1.medium", "cache.m1.small", "cache.m1.xlarge", "cache.m2.2xlarge", "cache.m2.4xlarge", "cache.m2.xlarge", "cache.m3.2xlarge", "cache.m3.large", "cache.m3.medium", "cache.m3.xlarge", "cache.m4.10xlarge", "cache.m4.2xlarge", "cache.m4.4xlarge", "cache.m4.large", "cache.m4.xlarge", "cache.m5.12xlarge", "cache.m5.24xlarge", "cache.m5.2xlarge", "cache.m5.4xlarge", "cache.m5.large", "cache.m5.xlarge", "cache.m6g.12xlarge", "cache.m6g.16xlarge", "cache.m6g.2xlarge", "cache.m6g.4xlarge", "cache.m6g.8xlarge", "cache.m6g.large", "cache.m6g.xlarge", "cache.r3.2xlarge", "cache.r3.4xlarge", "cache.r3.8xlarge", "cache.r3.large", "cache.r3.xlarge", "cache.r4.16xlarge", "cache.r4.2xlarge", "cache.r4.4xlarge", "cache.r4.8xlarge", "cache.r4.large", "cache.r4.xlarge", "cache.r5.12xlarge", "cache.r5.24xlarge", "cache.r5.2xlarge", "cache.r5.4xlarge", "cache.r5.large", "cache.r5.xlarge", "cache.r6g.12xlarge", "cache.r6g.16xlarge", "cache.r6g.2xlarge", "cache.r6g.4xlarge", "cache.r6g.8xlarge", "cache.r6g.large", "cache.r6g.xlarge", "cache.r6gd.12xlarge", "cache.r6gd.16xlarge", "cache.r6gd.2xlarge", "cache.r6gd.4xlarge", "cache.r6gd.8xlarge", "cache.r6gd.xlarge", "cache.t1.micro", "cache.t2.medium", "cache.t2.micro", "cache.t2.small", "cache.t3.medium", "cache.t3.micro", "cache.t3.small", "cache.t4g.medium", "cache.t4g.micro", "cache.t4g.small"]

Similar error for rds E3030 You must specify a valid value for DBInstanceClass (db.r7g.xlarge). Valid values are ["db.m1.large", "db.m1.medium", "db.m1.small", "db.m1.xlarge" .....

I suspect cfn-lint doesn't support latest 7th Generation instances. Note: Region- EU-West-1

@Abhinab-AY please make sure you are on the latest version. cache.r7g.xlarge is an option for CacheNodeType in eu-west-1. Also db.r7g.xlarge is available for AWS::RDS::DBInstance classes.

Also eu-west-1 now has cache.m7g.xlarge
