Worked on the hashicorp/terraform-provider-aws repository, focusing on enhancing the documentation for AWS SageMaker Domain resources. Updated the Markdown-based documentation to clarify that the default_space_settings argument is now optional, rather than required, aligning the provider’s user interface with current AWS capabilities. This docs-only change, implemented using Terraform and documentation best practices, aimed to improve API clarity and reduce onboarding friction for users configuring or upgrading SageMaker Domain. By maintaining consistency across the provider’s documentation, the update helped minimize confusion during setup and ensured that users have accurate, up-to-date guidance when working with Terraform and AWS infrastructure.
