"panic recover interface conversion: interface is *errors.errorString, not string" when sending get request #60

Closed kuzemkon closed 7 years ago

kuzemkon commented 8 years ago

I am trying to serve the app on vm ubuntu x64 using vagrant. After install Go v1.7.1, Node.Js v6.7.0 I set enviropment variables: export GOPATH=pwd export PATH=$PATH:$GOPATH/bin export GO15VENDOREXPERIMENT=1 cd bin export GOBIN=$(pwd) export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin. Then I was installed all dependencies runing make install and build it by make build. When I start the server using make serve, it start's successfull. Terminal shows me ==> 🌎 Listening on port 5001. Open up http://localhost:5001/ in your browser. , but when I making request in browser to localhost:5001 the terminal shows me 500 error of GET request and I received panic recover interface conversion: interface is *errors.errorString, not string stack trace 8250 bytes in my browser. I gave 4GB memory for vagrant, because, if I used less, I received "Cannot allocate memory". image

Hi @gameiro9k,

could you attach stack trace and diff which was applied(if any) here?
