SageMaker Studio projects in VpcOnly mode without internet access

Question

A customer is using SageMaker Studio in VpcOnly mode (VPC, protected subnets **without** internet access, **NO** NAT gateways). 
The all functionality is fine. However, when I try create a SageMaker projects - as described [here](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-projects-create.html), SageMaker Studio is unable to list the project templates (timeout and unspecified error) resulting in empty list of the available project templates.

Projects are enabled for the users - as described [here](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-projects-studio-updates.html). The problem is with project creation.

Is internet access (e.g. via NAT gateways) is needed for SageMaker projects?

Accepted Answer

Figured it out. SageMaker Studio projects need Service Catalog access and VPCE for `com.amazonaws.${AWS::Region}.servicecatalog`
