Hanging request

[Bost]

I execute two parallel requests from Heroku using (get url {:accept :json :debug true}). Sometimes, one of them - the one against http://covid-tracker-us.herokuapp.com/all never ends. I get neither an exception nor any timeout nor anything else. The other one - against https://covid.ourworldindata.org/data/owid-covid-data.json runs always fine. Can you tell me please, am I doing anything wrong? Thanks

If you need to see more, here my get-json function

You need to set the timeouts explicitly. The default value 0 is to block indefinitely:

• :connection-timeout
• :socket-timeout

See the documented examples in the README: https://github.com/dakrone/clj-http#get

I've been testing your advice for a while and it looks like it helps. Thanks, I'm closing this issue.

Glad to hear :)
