Terraformed AWS API 网关自定义域名抛出 403 Forbidden

Question

我正在尝试通过区域自定义域公开我的区域 API 网关的所有阶段。

问题

如果我直接卷曲我的 API 网关（即 https://xx.execute-api.eu-west-3.amazonaws.com/default/users），它可以工作，但如果我卷曲域名（即 [=14]，我会得到一个 403 =]).

配置

我的 Terraform 文件看起来像这样：

data "aws_route53_zone" "acme" {
  name         = "acme.com."
}

resource "aws_api_gateway_rest_api" "backend" {
  name        = "acme-backend-api"
  description = "Backend API"
  body        = "SOMETHING"

  endpoint_configuration {
    types = ["REGIONAL"]
  }
}

resource "aws_api_gateway_deployment" "backend" {
  rest_api_id = aws_api_gateway_rest_api.backend.id
  stage_name  = "default"

  lifecycle {
    create_before_destroy = true
  }
}

resource "aws_api_gateway_domain_name" "backend" {
  domain_name              = "api.acme.com"
  regional_certificate_arn = "arn:aws:acm:xx:certificate/xx"

  endpoint_configuration {
    types = ["REGIONAL"]
  }
}

resource "aws_route53_record" "backend" {
  name    = aws_api_gateway_domain_name.backend.domain_name
  type    = "A"
  zone_id = data.aws_route53_zone.acme.id

  alias {
    evaluate_target_health = true
    name                   = aws_api_gateway_domain_name.backend.regional_domain_name
    zone_id                = aws_api_gateway_domain_name.backend.regional_zone_id
  }
}

resource "aws_api_gateway_base_path_mapping" "backend" {
  api_id      = aws_api_gateway_rest_api.backend.id
  domain_name = aws_api_gateway_domain_name.backend.domain_name
  # No stage_name: expose all stages
}

根据 Terraform api_gateway_domain_name and api_gateway_base_path_mapping 例子，应该没问题。

我也关注了很多howtos，我有这些要素：

证书
A 记录到 API 自定义域
到部署阶段的映射（如果你直接调用它就有效）

我miss/do错了什么？
