Chapter 13 - Rate limiter route service
Hi @spgreenberg
I deployed web-ui app & roster app (available as rest-backend service and bind to web-ui) . I can add people and view them in web-ui.
Later i deployed rate-limiter app (available as rate-limiter-service and bind to web-ui's route web-ui-hilarious-jackal-jc.mybluemix.net)
cf brs mybluemix.net -n web-ui-hilarious-jackal-jc rate-limiter-service
Once i bind the rate limiter route service then my web-ui's home page, starts giving "502 Bad Gateway: Registered endpoint failed to handle the request."
Could you please advise where i am going wrong ? Thank you.
Below is the env for my web-ui:

Adding on some more details:
I get 404 when i reach the route service app (http://rate-limiter-sudha.mybluemix.net/), i am not sure whether this is the route cause of my 502 issue.As per the logs i can see the traffic go from route-service to web-ui but web-ui responds with a 502.
