Hi everybody,

When I tried to do something similar to this code

```auto
 var uri = "https://<mypage>.com/"
        var sendRequest = function() {
            var options = {
                method: 'POST',
                headers: {
                    'Accept': 'application/json',
                    'Content-Type': 'application/json'
                },
                body: JSON.stringify(params)
            };
            fetch(uri, options).then(function(response) {
                var data = JSON.stringify(response)
                debug_log(data);
            }, function(error) {
                debug_log(error);
            });
        };

```

I got this exception

```auto
Fetch error System.UriFormatException: Invalid URI: The format of the URI could not be determined.
   at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
   at System.Uri..ctor(String uriString)
   at System.Net.WebRequest.Create(String requestUriString)
   at MyHttpLib.HttpRequest..ctor(String url)
   at Uno.Net.Http.Implementation.CilHttpRequest..ctor(IHttpMessageHandlerRequestCallbacks requestCallbacks, String method, String url)
   at Uno.Net.Http.Implementation.CilHttpRequest.Create(IHttpMessageHandlerRequestCallbacks requestCallbacks, String method, String url)
   at Uno.Net.Http.HttpMessageHandlerRequest..ctor(HttpMessageHandler handler, String method, String url, IDispatcher dispatcher) in C:\ProgramData\Uno\Packages\Uno.Net.Http\0.26.9\$.uno#2:line 247

```

here is an example of the body

{“location”:“somewhere”,“date”:“14\nTHU\nAPR”,“time\_slot”:“10 AM- 11 AM”,“check”:“true”}

That should work, so I need some more details. Could you ping me (@bondehagen) on the slack community channel, so I can take a look at you project?
