Terraform Core Version

1.0.0

AWS Provider Version

3.70.0, 4.51.0

Affected Resource(s)

• aws_autoscaling_group

Expected Behavior

• Similar to what has been done for version parameter in launch_template_specification blocks:

  • The provider source code must implement a default value for the version parameter in the top-level launch_template block.

Actual Behavior

• As per the terraform reference, the default value for the version parameter (in launch_template block) is $Default

• However, the provider code does not implement a default value for this parameter (Refer: autoscaling_group.go#L217)

• Due to this, the version is passed as empty. When this Autoscaling group is viewed on the AWS console, the Console is unable to display the details of launch template as it does not know which version of the template should be read.

  

• The edit section of the launch template also has nothing selected due to the missing version.

• The launch_template_specification blocks under 'mixed_instances_policy' have the same schema as launch_template, but they correctly implement a default value in the code (Refer: autoscaling_group.go#L327)
