[BUG] Cannot map backend roles

[elchananmizrachi]

Hi,

Trying to map roles to backend, after enabling FGAC on OpenSearch 2.3, using this block:

resource "opensearch_roles_mapping" "mapper" {
  role_name   = "logs_writer"
  description = "Mapping AWS IAM roles to ES role"
  backend_roles = [
    "arn:aws:iam::123456789012:role/lambda-call-opensearch",
    "arn:aws:iam::123456789012:role/run-containers",
  ]
}

provider version 2.0.0-beta.1

Getting:

│ Error: invalid character '<' looking for beginning of value

Did someone came across this issue and have a solution?

I have the same issue but with opensearch_monitor resource

Here is the debug log. Is it possible to see a content of unexpected data?

Could it be similar to this one?
stripe/stripe-go#642 (comment)

Or this one
grafana/k6#773

Edit:
It definitely not the first one as provider doesn't make any connections to OpenSearch. Then it's, probably, the second, however, json linter doesn't return any errors.

Edit2:
I tried to copy/paste example from here but still have the same issue
