When I am running a program which is for a web response I am getting a run
time error as follows:
http: panic serving 127.0.0.1:43802: runtime error: invalid memory address
or nil pointer dereference
goroutine 6 [running]:
net/http.(*conn).serve.func1(0xc4200a4a00)
/usr/lib/go-1.10/src/net/http/server.go:1726 +0x11b
panic(0x9b5360, 0xd99230)

0xc420022100, 0x0, 0x0, 0x0)
The code of main file is as follows:
func main() {
router := httprouter.New()
router.RedirectTrailingSlash = true
c := cors.New(cors.Options{
AllowedOrigins: []string{"*"},
AllowedMethods: []string{"GET", "POST", "OPTIONS", "Authorization"},
AllowedHeaders: []string{"*"},
AllowCredentials: true,
})
router.GET("/create", StoreAndGetHash)
router.GET("/read/:hashvalue", GetFile)
router.GET("/appdata/:appID", ReadPeer)
router.GET("/update", UpdateAndGetHash)
router.GET("/createdir", GetDir)
router.GET("/newkey", GetNewKey)
log.Fatal(http.ListenAndServe(":3000", c.Handler(router)))
}
I am working on ubuntu
