I'd like to display server errors in notifications. By default, the notification says "Bad request" when a 400 is returned. I've tried to change the behaviour with the onFailure (https://marmelab.com/react-admin/CreateEdit.html#onfailure), but the argument error always seems to be a generic HttpError(). The message is lost somewhere, somehow.

export const MyEdit = (props) => {
  const refresh = useRefresh();

  const onFailure = (error) => {
    console.log('ERROR stack trace', error);  // show 'Error'
    console.log('ERROR stack trace', error.stack);  // show 'Error'
    refresh();
  };


  return (
    <Edit
      onFailure={onFailure}
      {...props}
    >
      <SimpleForm>
        <TextInput
          source="full_name"
          fullWidth
        />
        <TextInput
          source="email"
          fullWidth
        />
      </SimpleForm>
    </Edit>
  );
};

The response on the server side is usually something like that

{
  field: [
    error_message_1,
    error_message_2,
    ...,
    error_message_n
  ]
}

With the Chrome debugger, it seems that my problem should come this class:

var HttpError = /** @class */ (function (_super) {
    __extends(HttpError, _super);
    function HttpError(message, status, body) {
        if (body === void 0) { body = null; }
        var _this = _super.call(this, message) || this;
        _this.message = message;
        _this.status = status;
        _this.body = body;
        Object.setPrototypeOf(_this, HttpError.prototype);
        _this.name = _this.constructor.name;
        if (typeof Error.captureStackTrace === 'function') {
            // Enter here
            Error.captureStackTrace(_this, _this.constructor);
        }
        else {
            _this.stack = new Error(message).stack;
        }
        // Returns an empty Error();
        _this.stack = new Error().stack;
        return _this;
    }
    return HttpError;
}(Error));

It returns an empty Error() and the stack does not contain values of previous message, body or status.

So how can I display the server message? Any help would be appreciated.

Just in case: Chrome 95: React-Admin: 3.19
