!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform.
A crash log has been placed at "crash.688954863.log" relative to your current
working directory. It would be immensely helpful if you could please
report the crash with Terraform[1] so that we can fix this.

When reporting bugs, please include your terraform version. That
information is available on the first line of crash.log. You can also
get it by running 'terraform --version' on the command line.

SECURITY WARNING: the "crash.688954863.log" file that was created may contain

Expected Behavior

Actual Behavior

Steps to Reproduce

Additional Context

N.B. This is not the usual AWS Provider but is an under-development version using https://github.com/hashicorp/terraform-plugin-framework (and hence protocol v6).

The resource's schema includes a SingleNestedAttribute:

		"insights_configuration": {
			Attributes: schema.SingleNestedAttributes(
				map[string]schema.Attribute{
					"insights_enabled": {
						// Property: InsightsEnabled
						Description: "Set the InsightsEnabled value to true to enable insights or false to disable insights.",
						Type:        types.BoolType,
						Optional:    true,
					},
					"notifications_enabled": {
						// Property: NotificationsEnabled
						Description: "Set the NotificationsEnabled value to true to enable insights notifications. Notifications can only be enabled on a group with InsightsEnabled set to true.",
						Type:        types.BoolType,
						Optional:    true,
					},
				},
			),
			Optional: true,
		},
