Accepted, 3 points.

Current implementation was done some time ago and works for design challenges only. The fix should ensure that it also works properly for development challenges (and, if possible, the same code is used both for design and dev challenges to download submissions).

@sdgun @birdofpreyru
I start with NODE_ENV=production npm start on my local machine & navigate to http://local.topcoder-dev.com:3000/challenges/30059030/my-submissions but show nothing

and I see a error occurs on the console

Failed to get challenge details! TypeError: Cannot read property 'track' of undefined

    at process._tickCallback (internal/process/next_tick.js:188:7)

While the http://community-app.topcoder.com/challenges/30059030/my-submissions (only host & port changed) shows my submissions:

Is there any configuration I missed?

[birdofpreyru]

@tilumi Yes, for production backend you should:

1. Permit node to listen on port 80
2. NODE_ENV=production PORT=80 npm run dev (npm run dev is better cause it start in development mode, with hot module reloading).
3. And then you should access as local.topcoder.com

Ok, it works, thanks!

Hi, @birdofpreyru
Is there any backend API documentation?

[birdofpreyru]

@tilumi well, it is fragmented (different places for different pieces of the backend).
for this, just check in the existing code, how submissions are downloaded at challenge results tab of challenge details page. Basically, for dev challenges, the download url is just stored in the redux for each submission. For design ones, we have to compose an URL to a legacy studio backend, using challenge ID.

OK, thanks a lot
