WSO2 API Manager /services/... throw a NullPointerException - wso2

Question

I have the WSO2 API Manager running on a Windows 2012 R2 server and all dashboard URL's like https://localhost:9443/store,https://localhost:9443/carbon,https://localhost:9443/publisher work fine. But when I configure and deploy (in the carbon.super tenant) the example WeatherAPI web service and try to reach it via the /services/... URL i.e.:
https://localhost:9443/services/weather/1.0.0/*?q=Amsterdam
I get the following error page returned:

When I create my own web service in a tenant and deploy it, I get the same error. So I probably misconfigured something, but don't know where to look.
All paths below /services/... seem to return this error page. I checked the log files in the [WSO2]/repository/logs directory, but they don't show any errors.

Answer 1

You are trying to access the services from the servlet port 9443. Try with the 8280 port . However, the endpoint of the API in APIM does not look like as you mention. Check the example given in the official WSO2 documentation
