Unable to create Http Health Check from config fil

I have been trying to create a http health check for a REST service using the config file.

While loading the consul, it read the service details from the config file and that is reflected in 8500 Web UI.

But it did not add the health check details for that service.

No error is displayed too when the health check is along with the service definition (Case 1).

But it notified an error when tried to give the health check config seperatly. (Case 2)

However I can able to successfully add a http health check when added via rest api. (Case 3)

Health Check with service details:- (Case 1)

{
"service": {
"id":"somename",
"name":"nameofthissevice",
"service": "myservice",
"address": "127.0.0.1",
"port": 62133,
"enableTagOverride": false,
"check": {      
"HTTP": "http://127.0.0.1:62133/Service1.svc/MyService/PingMe",
"Interval": "5s"    
}
}
}

Health Check config alone:- (Case 2)

"check": {    
"http": "http://127.0.0.1:62133/Service1.svc/MyService/PingMe",
"interval": "5s",
"timeout": "150s",
"ttl" : "100s"
}

Health Check via Code in C#:- (Case 3)

var check = new AgentServiceCheck()
        {
            Interval = TimeSpan.FromSeconds(10),
            HTTP = "http://127.0.0.1:62133/Service1.svc/MyService/PingMe",
            DeregisterCriticalServiceAfter = TimeSpan.FromSeconds(10)
        };

var srv = new AgentServiceRegistration()
        {
            XXXXX,
            Check = check
        };

var result = client.Agent.ServiceRegister(srv).GetAwaiter().GetResult();

I am using Consul V.0.9.0 for windows.

Here is my consul log.

Could anyone give some info on this one.

Thx

case 1 has upper case HTTP key which seems like a mistake - https://www.consul.io/docs/agent/checks.html

case 2 - if this is your entire check file, the JSON is invalid (wrap it with { }). you may also want to link it to the service by specifying a service_id
