  1. Hi Bro, I need your help.

    I'm writing this YAML.

    Mappings:

    InstanceTypeMap:

    sqlserver-ee:

    InstanceClasses:

    – db.t3.small

    – ….

    – ….

    DBInstanceClass:

    Type: String

    AllowedValues: !FindInMap [InstanceTypeMap, !Ref DBEngine, InstanceClasses]

    But I got this error when I valid this YAML

    `

    The template contains errors.: Template format error: Every AllowedValues member must be a list.

    `
