502 Bad Gateway - no resolver defined

[brylie]

I was able to get a basic query to work using the Getting Started guide, after some minor tweaking of the URL parameters.

When I add a second API and call its URL, I get a 502 Bad Gateway.

After further consideration, I realized this seems like a router issue. The tail of the router_error.log contains the following:

2014/11/13 10:12:37 [error] 20278#0: *209 no resolver defined to resolve api_umbrella_6de92ad1-1994-4fbf-9faa-bec521025e70_backend, client: 109.240.164.253, server: _, request: "GET /tags HTTP/1.1", host: "api.avoindata.net"

How do I define a resolver to resolve api.avoindata.net?

OK... I found out where I went wrong. On the Step 2: Add a new backend: I neglected to enter a server. Oops :)

As a quick heads up, the new v0.7 packages that have been released should solve this issue with much better error validation surrounding the API Backend forms. Now you won't be able to save the form without filling in the backend section (and we've made a variety of other changes to try to improve the flow and error handling).
