This is always indicative of a bug within the plugin. It would be immensely helpful if you could report the crash with the plugin's maintainers so that it can be fixed. The output above should help diagnose the issue. ### Expected Behavior VPN Gateway should be created successfully. ### Actual Behavior Apply fails with error. ### Steps to Reproduce terraform init terraform apply ### Additional Context _No response_ ### References _No response_
