SSE and Server Errors

[elbrujohalcon]

When an SSE endpoint returns an error (e.g. status code 500), it gets listed as an event on shotgun:events.

As an example, consider this code from fiar:

    {ok, Pid1} = shotgun:open("localhost", 8080),

    {ok, Ref1} = shotgun:get( Pid1
                            , "/matches/" ++ Mid ++ "/events"
                            , Headers2
                            , #{ async => true
                               , async_mode => sse}),

    api_call(put, "/matches/" ++ Mid, Headers1, Body),

    [XX] = shotgun:events(Pid1),

    io:format("~p~n", [XX]).

That prints out…

#{headers => [{<<"connection">>,<<"keep-alive">>},
  {<<"server">>,<<"Cowboy">>},
  {<<"date">>,<<"Fri, 03 Oct 2014 13:32:19 GMT">>},
  {<<"content-length">>,<<"0">>}],
  status_code => 500}

It should either throw an exception instead, or shotgun:events should return a response description element (with the headers, status, etc.) besides the list of events.

@Euen keep an eye on this one :)

@elbrujohalcon I'm not sure what return value this describes:

... or shotgun:events should return a response description element (with the headers, status, etc.) besides the list of events.

[elbrujohalcon]

@jfacorro try to get the events from an endpoint that returns 401 and you'll see

@elbrujohalcon I meant I'm not sure the desired return value this describes:

... or shotgun:events should return a response description element (with the headers, status, etc.) besides the list of events.

@jfacorro maybe besides the reference you get when you start such a request… you can also get the headers, status code, etc.
