Error: The terraform-provider-maas_v1.3.1 plugin crashed! [cannot import maas_machine resource]

Hi,

I got this error when trying to import a maas_machine resource:

Error: The terraform-provider-maas_v1.3.1 plugin crashed!

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.

The problem seems to be in the "panic: interface conversion: interface {} is []interface {}, not string" part.
Ask for help.

in main.tf

module "prod_compute_machine" {
 source          = "./modules/machine"
 
 for_each        = local.prod_compute_machines
 ...

and local.tf

 locals {
     prod_compute_machines = {
         "dc1-compute-1" = {

Thank you.

Hi @Seochokid

Thank you for opening this issue. I would like to ask you if the maas_machine for which the error is raised, has power parameters of type IPMI.

Yes the maas_machine power_type where the error occurred was ipmi.

Hi @Seochokid
The fix for power parameters was introduced in #96
We are planning to release a new version of provider in the upcoming weeks.
