When I’m sending POST requests in my Angular application with the body beeing a boolean, in the case it is true it is correctly send in the payload, in the case it is false no payload is send with the request.

constructor(
    public readonly http: HttpClient,
  ) {
  const requestBody = false;
  http..request({
      method: 'POST',
      url: '/locked',
      body: requestBody,
      mediaType: 'application/json',
    });
}

Is there a way to send boolean base types directly with false value?
