Thanks for reaching out. The ValidationException is being returned from the underlying SageMaker UpdateSpace API. I brought this up with a member of the SageMaker team who confirmed that this is the expected behavior. You cannot update AppType once the space is created. They acknowledged that this could be better clarified in the documentation, and they took an action item to improve the docs. Once the API documentation is updated then the changes will be reflected in the Boto3 command docs as well.

Hi @tim-finnigan
Thank you for your help.
However, such behavior causes both CloudFormation and Terraform to fail on space update with the error mentioned above.
