@phadej: "Strings with / (normal slash) seems to result into 404 error"

• When I run the service locally (runhaskell backend/Search.hs), it works fine: https://user-images.githubusercontent.com/4061728/106886138-9737c500-66f4-11eb-94d9-2ce034cbc725.png

• On the other hand, the deployed version fails: https://user-images.githubusercontent.com/4061728/106886303-c6e6cd00-66f4-11eb-9e8b-88d2e6e12f54.png

The only difference that I know of is that in the deployed service there's nginxin the middle:

    services.nginx.virtualHosts.hackage-search = {
      locations."/".proxyPass =
        if ! isNull cfg.socket
        then "http://unix:${cfg.socket}:/"
        else "http://localhost:${toString cfg.port}/";

      locations."/static/fonts/".alias = "${cfg.package}/fonts/";

But I don't know how to run the service locally to check if it's indeed the cause. @zhenyavinogradov Could you look into this? Thanks.

[zhenyavinogradov]

Right, it's nginx replacing urlencoded characters with real ones, I'll see how we can fix it

You won't believe this one simple trick https://github.com/serokell/hackage-search/pull/19

Did it really help? https://hackage-search.serokell.io/?q=%2F still fails.

That fix is not deployed yet, the service is part of the system configuration, so we have to update it in the -infra repo: https://github.com/serokell/pegasus-infra/pull/11. I need a review from ops to deploy it.
