Plugin crashes when importing top-level dataset

[Razaekel]

Attempting to import the Top level dataset (System Dataset Pool) causes the plugin to crash with an 'out of bounds' error.

truenas_dataset.main: Importing from ID "main"...
truenas_dataset.main: Import prepared!

Error: The terraform-provider-truenas_v0.11.1.exe 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.

I can confirm this. I get the same error when trying to get the top-level dataset.
When adding a sub dataset it works flawless.
e.g.:

data "truenas_dataset" "test" {
  dataset_id = "Tank"
}

[yuqo2450]

Ok I think Iw as wrong. And maybe @Razaekel as well. It considered the pool to be the top-level dataset. WHat is obviously not correct.
The dataset ID is pool/dataset.

[ArdRay]

Correct, top-level import or data query fails. A friendlier error description would be welcome.
