[Bug] Since 0.11.12, elasticstack_kibana_data_view crashing with "panic: runtime error: invalid memory address or nil pointer dereference"

[gavD]

Describe the bug
Our Terraform works fine with 0.11.11 and prior versions.

However, if we use 0.11.12, we get errors whenever using elasticstack_kibana_data_view

We suspect it's something to do with this change #881 which reworks dataview

To Reproduce
Steps to reproduce the behavior:

1. TF configuration used: hard to say what's relevant and what's not, but here's our TF:

resource "elasticstack_kibana_import_saved_objects" "settings" {
  overwrite     = true
  file_contents = local.advanced_settings_content
}

resource "elasticstack_kibana_data_view" "index_pattern" {
  for_each = var.index_patterns

  override = true

  data_view = {
    allow_no_index  = true
    id              = each.key
    name            = each.value.title
    time_field_name = each.value.time_field
    title           = each.value.title
  }

  depends_on = [elasticstack_kibana_import_saved_objects.settings]
}

3. TF operations to execute to get the error: terraform apply
4. See the error in the output
   Expected behavior
   It should not crash
