Description

Bigquery reservations can only use alphanumeric characters and dashes. If you try to include something else (like an underscore) you will get the following unhelpful error from the API:

{
  "error": {
    "code": 400,
    "message": "Malformed reservation.",
    "status": "INVALID_ARGUMENT"
  }
}
