terraform-provider-elasticsearch: "Plugin did not respond" error during applying opendistro_role

Hello! Thank you for your provider, it is really convenient and helpful!

Unfortunately I faced multiple issues with it, the most frustrating is “Plugin did not respond”.

Terraform v1.1.4
on darwin_amd64
+ provider registry.terraform.io/hashicorp/aws v3.74.1
+ provider registry.terraform.io/hashicorp/http v2.1.0
+ provider registry.terraform.io/hashicorp/null v3.0.0
+ provider registry.terraform.io/hashicorp/random v3.0.1
+ provider registry.terraform.io/phillbaker/elasticsearch v2.0.0-beta.4

Here is my tf-code example:

provider "elasticsearch" {
  url                 = "https://search-{{ ES DNS NAME }}.eu-west-1.es.amazonaws.com"
  aws_assume_role_arn = module.es.es_admin_role_arn
  healthcheck         = false
}

...

resource "elasticsearch_opendistro_role" "this" {
  role_name   = var.role_name
  description = var.issue

  cluster_permissions = ["cluster_composite_ops"]

  index_permissions {
    index_patterns  = var.index_patterns
    allowed_actions = ["unlimited"]
  }
}

resource "elasticsearch_opendistro_user" "this" {
  username    = var.user_name
  password    = local.user_password

  lifecycle {
    ignore_changes = [password]
  }
}

And here is the error example(I’m getting multiple errors with different roles/users):

╷
│ Error: Plugin did not respond
│ 
│   with module.opendistro_groups["{{ GROUP NAME }}"].elasticsearch_opendistro_user.this,
│   on ../modules/opendistro/main.tf line 29, in resource "elasticsearch_opendistro_user" "this":
│   29: resource "elasticsearch_opendistro_user" "this" {
│ 
│ The plugin encountered an error, and failed to respond to the plugin.(*GRPCProvider).ReadResource call. The plugin logs may contain more details.
╵

Error: The terraform-provider-elasticsearch_v2.0.0-beta.4 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.

A couple of things from debug log: https://gist.github.com/sergkondr/c88848f7219ac7b72e0bf62854bed97c
