Updating Atlas resources using AWS Cloudformation

Hi there, i’m trying to get started using cloudformation to deploy and manage a cluster. I can successfully deploy a cluster using cloudformation, however any time i want to make any updates to the Atlas resources (Database User, Cluster Details etc…), using cloudformation i get the following error:

Resource handler returned message: “Unable to complete request: runtime error: invalid memory address or nil pointer dereference” (RequestToken: 5e5de241-0d4e-aa67-67c0-c7287978271c, HandlerErrorCode: GeneralServiceException)

I have installed all of the cloudformation resources using the get-setup shell script found here: GitHub - mongodb-developer/get-started-aws-cfn: Get started using MongoDB Atlas with AWS CloudFormation today!

I’m operating in the us-east-1 region.

What am i doing wrong? or is it not possible to update the Atlas resources via cloudformation after their initialisation?
