2025-09-18 18:48:57.303Z Error: Invalid registry module source address

Environment

• Coder deployment: EKS cluster
• Template: kubernetes-devcontainer (from workshop materials)

Additional Context

This appears to be a formatting issue with the module source address in the template. The current format uses 4 components when Terraform expects 3 or 4 in a specific pattern.
