Hi after reviewing the source code I found an implementation of the request method as follows:

    @abstractmethod
    def request(self, method, url, headers=None, raise_exception=True, **kwargs):
        """Main method for routing HTTP requests to the configured Vault base_uri. Intended to be implement by subclasses.

        :param method: HTTP method to use with the request. E.g., GET, POST, etc.
        :type method: str
        :param url: Partial URL path to send the request to. This will be joined to the end of the instance's base_uri
            attribute.
        :type url: str | unicode
        :param headers: Additional headers to include with the request.
        :type headers: dict
        :param kwargs: Additional keyword arguments to include in the requests call.
        :type kwargs: dict
        :param raise_exception: If True, raise an exception via utils.raise_for_error(). Set this parameter to False to
            bypass this functionality.
        :type raise_exception: bool
        :return: The response of the request.
        :rtype: requests.Response
        """
        raise NotImplementedError

I am new at python but it seems like the class isn't already implemented, instead it is just raising an error, then this is why the call is working by curl but not by py

Thanks all for your help, I really appreciate your time.
