Cannot use the listGroupResources in AWS SDK

Question

I want to find the RDS instances in my dev resource group, I have the following code:

  const params = {
    GroupName : "dev",
    Filters : [
      {
        Name : "resource-type",
        Values : ["AWS:RDS:DBInstance"]
      }
    ]
  }

  resourcegroups.listGroupResources(params)

But get this:

(node:69536) UnhandledPromiseRejectionWarning: BadRequestException: 1 validation error detected: Value '[AWS:RDS:DBInstance]' at 'filters.1.member.values' failed to satisfy constraint: Member must satisfy constraint: [Member must have length less than or equal to 128, Member must have length greater than or equal to 1, Member must satisfy regular expression pattern: AWS::[a-zA-Z0-9]+::[a-zA-Z0-9]+]

Answer 1

Ok that was dumb should be Values: ["AWS::RDS::DBInstance"] with :: instead of :
