  on example.tf line 2:
   2: 	name                = "env_name_underscores"

Why

When attempting to create the resource, Terraform will return the error:

Error: InvalidParameterValue: Value env_name_underscores at 'EnvironmentName' failed to satisfy 
constraint: Member must contain only letters, digits, and the dash character and may not start 
or end with a dash
status code: 400

How To Fix

Ensure your environment name consists only of letters, digits, and the dash character, and does not start or end with a dash. The regex used is ^[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]$
