WSO2 APIM Install and Deployment HTTP 500 on /services/

Question

We're trying to deploy WSO2 to our cloud environment. I used the provided cloudformation templates to deploy to AWS. I try to access the Carbon Server UI but I receive a 500 error code.

When I look in wso2carbon.log I see this error correlated with the request that generates a 500 error code.

        ... 50 more

I believe this means that there is no API to request which is passing a null value that is trying to be de-referenced later. But, I'm not sure if that's correct.

Any help understanding the error would be appreciated!

It seems you have mapped the wrong ports. Management console, admin services and all the UI components(Devportal, Publisher) etc. are exposed via port 9443. The Gateway(API calls) are exposed via ports 8243 for HTTPS and 8280 for HTTP traffic. Hence check the port mappings in your Loadbalancer.
