Hi David_Boschmann, thanks for your comment. There are a few possibilities that may cause this error which I have highlighted below. If these don’t unblock you directly, feel free to create a new issue in our GitHub repo and can have someone help you further.
- Activate the 3rd party extension for MONGODB::ATLAS::PROJECT in each AWS region and from each AWS account that you wish to deploy from
- Ensure you have sufficiently strong AWS IAM Activation Role attached to this 3rd party extension. For sample IAM Role see here
- Ensure your activated 3rd party public extension matches name exactly to MONGODB::ATLAS::PROJECT (you may need to delete private extension if this namespace is already occupied)
- Ensure your MongoDB Atlas Programmatic API Keys (PAKs) being used with CloudFormation have sufficiently strong permissions (Organization Project Creator or Organization Owner)
- Ensure your MongoDB Atlas PAKs have correct IP Address / CIDR range access, for testing purposes you can with caution open keys to all access by adding “0.0.0.0/1” and “128.0.0.0/1”
Hope this helps!
