recv: failed (Unknown error) messages in rest wai example

cnd opened this issue 8 years ago · comments

When I run rest wai example

generate some client and then use _run "localhost" (User.list []) it works and I can see full info loaded by example but in rest-wai console I'm getting messages: recv: failed (Unknown error)

win 10 x64 ghc 8.0.1

What is the _run function? And how are you running the server (i.e. what command to start it)?

I just tried and can't reproduce here on OS X.

@hesselink I've pushed example on github to reproduce https://github.com/Heather/NeverLand/blob/master/client/src/APITest.hs#L12 it's really minimal based on rest-example

Thanks, that's really useful! I've built the main package with -fwai, built the client, and ran both executables. This printed the following in the client:

PluginInfo {name = "plugin 1"}
PluginInfo {name = "plugin 2"}
PluginInfo {name = "plugin 3"}

In the server it printed

Starting warp server on http://localhost:3000

And nothing else. So I'm not seeing the messages you're seeing. It could be a windows specific issue, I guess. Sadly I don't know much about windows.

@hesselink yes, it works the same for me but after Starting warp server on http://localhost:3000 line I saw recv: failed (Unknown error) message (however it doesn't break server), I think I will invest some more time to get more related information and will post here as soon as I will find something related.
