Registration of non-Java App following Eureka API Documentation - Issue - netflix-eureka

Question

I have Eureka running in my localhost:8090 . I have independent Java Apps registered in that Eureka and I am able to access them with my Zuul URL which is registered to that Eureka as well.
Now I am have another Python(3.7.3)+Flask App that I am trying to register in same Eureka and access that through same Zuul URL.
My Python app runs fine in local through a DOCKERFILE with these commands -
EXPOSE 8443
CMD ["python", "PythonFlaskSample.py"]
This opens a web-page with this URL -
http://localhost:8443/home
Then to register this App in Eureka, I followed this documentation -
https://github.com/Netflix/eureka/wiki/Eureka-REST-operations
and
https://automationrhapsody.com/json-format-register-service-eureka/
Also trying same through REST clients with POST URL as -
http://localhost:8090/eureka/v2/apps/PythonFlaskApp
Content-Type: application/json
{
"instance": {
"hostName": "localhost",
"app": "PythonFlaskSample",
"vipAddress": "localhost",
"secureVipAddress": "localhost",
"ipAddr": "<Which IP>????",
"status": "STARTING",
"port": {"$": "8090", "#enabled": "true"},
"securePort": {"$": "8443", "#enabled": "true"},
"healthCheckUrl": "http://localhost:8090/health",
"statusPageUrl": "http://localhost:8090/info",
"homePageUrl": "http://localhost:8090",
"dataCenterInfo": {
"#class": "com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo",
"name": "MyOwn"
},
}
}
But it is throwing a 405 and no other clue for what happened in Restlet client or Postman.
When I try to put the JSON Payload in python file and use POST from there,
request_body = {
"instance": {
"hostName": "localhost",
"app": "PythonFlaskSample",
"vipAddress": "localhost",
"secureVipAddress": "localhost",
"ipAddr": "<Which IP>????",
"status": "STARTING",
"port": {"$": "8090", "#enabled": "true"},
"securePort": {"$": "8443", "#enabled": "true"},
"healthCheckUrl": "http://localhost:8090/health",
"statusPageUrl": "http://localhost:8090/info",
"homePageUrl": "http://localhost:8090",
"dataCenterInfo": {
"#class": "com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo",
"name": "MyOwn"
},
}
}
data=json.dumps(request_body)
url="http://localhost:8090"
response = requests.post(url,data=json.dumps(request_body), headers = {'Content-type':'application/json'}).json()
print(response)
it shows following error-
docker run -p 8443:8443 dockerpython {'timestamp': 1555717403333,
'status': 405, 'error': 'Method Not Allowed', 'exception':
'org.springframework.web.HttpRequestMethodNotSupportedException',
'message': "Request method 'POST' not supported", 'path': '/'}
What am I missing ?

This is an error with Eureka API documentation in - https://github.com/Netflix/eureka/wiki/Eureka-REST-operations. Once I tried same REST URLs without "/v2" , everything worked fine.enter image description here
