Panic Output
No response
Expected Behavior
Expected behaviour is for a Linode instance to be created with the interface specified in the linode_interface resource.
I was testing this with a VPC interface, however, even running the example that creates a public interface fails.
https://registry.terraform.io/providers/linode/linode/latest/docs/resources/interface
"This resource is specifically for Linode interfaces. If you are interested in deploying a Linode instance with a legacy config interface, please refer to the linode_instance_config resource documentation for details."
This indicates that this is the new way to setup interfaces, however, as this did not work I had to use the legacy way that works fine.
Actual Behavior
404 error and only these resources are created:
linode_instance.my-instance
linode_instance_disk.boot
Steps to Reproduce
Just run the documentation example:
https://registry.terraform.io/providers/linode/linode/latest/docs/resources/interface#complete-example-with-linode
