API explorer 500 error on large API responses

Hi @trkrameshkumar,

We're aware of some general infrastructure issues affecting this endpoint. Are you consistently getting failures, or can you work around this by just retrying? Can you provide us with timestamps of exactly when you saw failures?

We are seeing the same thing. 500 Error both in the API Explorer and in Postman. We're unable to get a response from Topictree, and Exercises

Hi all,

These endpoints both serve very large responses so we do sometimes have transient errors if you don't hit a cache. Can you work around this by retrying in case of a server error? It looks like we have a fairly small percentage of requests failing so that should generally work; while I'd certainly like to solve these problems I doubt we'll ever get the error rate to 0 given how much data we're returning in these endpoints.

Can you give me an example request that succeeds? I'm unable to get a success from the exercises API given one or two filters. Such as this request:

Ah! It looks like this is a bug in our API explorer, which is why I wasn't seeing many failures in our main logs. If you hit www.khanacademy.org it should work; we'll look into why the API explorer isn't working right.
