AccessContextManagerのCloudAPIを叩いた際に以下のエラーが出た

curl -H "Authorization: Bearer "$(gcloud auth print-access-token) "https://accesscontextmanager.googleapis.com/v1/accessPolicies?parent=organizations/12345"

{
  "error": {
    "code": 403,
    "message": "Your application has authenticated using end user credentials from the Google Cloud SDK or Google Cloud Shell which are not supported by the accesscontextmanager.googleapis.com. We recommend configuring the billing/quota_

    "status": "PERMISSION_DENIED"

}

billingの設定が通ってないのか、ヘッダーに X-Goog-User-Project: my-project を入れることで解決

curl -H "X-Goog-User-Project: my-project" -H "Authorization: Bearer "$(gcloud auth print-access-token) "https://accesscontextmanager.googleapis.com/v1/accessPolicies?parent=organizations/12345"
