Authorization error

[alelapi]

Hello all,
We are experiencing a 403 authorization error when using this provider. Our cloud provider is GCP.

We are trying to retrieve information about a CircleCI project using Terraform. When making an HTTP request directly, it works (i.e., without using this provider).

data "http" "circleci_project" {
  url = "https://circleci.com/api/v2/project/bb/org_name/${var.project_name}"

  request_headers = {
    "Circle-Token" = data.google_secret_manager_secret_version.circleci_robot_personal_access_token.secret_data
    "Accept"       = "application/json"
  }
}

When using the provider's data resource, we encounter a 403 Authorization error:

terraform {

  required_version = ">= 1.0"

  required_providers {
    circleci = {
      source = "CircleCI-Public/circleci"
      version = "0.2.0"
    }
  }
}

provider "circleci" {
  key  = data.google_secret_manager_secret_version.circleci_robot_personal_access_token.secret_data
}

data "circleci_project" "self" {
  slug = "bb/org_name/${var.project_name}"
}

This is the error we get:

│ Error: Unable to Read CircleCI project settings
│ 
│   with module.circleci_identity.data.circleci_project.self,
│   on ../main.tf line 7, in data "circleci_project" "self":
│    7: data "circleci_project" "self" {
│ 
│ 403 Forbidden: {"message":"Permission denied."}

Is this a bug or I'm doing something wrong?
