Are there known issues with self-signed certificates and the HTTP client? I found a Vizio SmartCast API that I’m trying to create a plug-in for a SoundBar so that I can get discrete On/Off commands and feedbacks. I have verified through curl (windows command line) and postman but when I try with both the designer and app I get an error “No public methods with the specified arguments were found.” I can see the traffic in Wireshark (error below) (URL hardcoded below while troubleshooting)
functionURL = mediaCommandURLMappings["PowerMode"]
var url =baseURL + functionURL
var Headers = {'Content-Type':'application/json',
'Content-Length': url.length }
console.log(" URL... https://"+ host + ":" + port + functionURL);
//response =
try {
response = http.get("https://10.37.250.60:9000/state/device/power_mode" );
sleep(250); // sleep briefly just to make sure we get the whole response
//response = response.trim();
console.log("GetStatus called..." + response);
} catch (error) {
console.log(error);
}
