Can you clear your mod cache and try again?

[schooltech]

I followed your method, just set up websocekt, and it was fine, but in my project, after cleaning the mod cache, the same error occurred, and my imported library looks like this: `module fiber-app

but the tag is there https://pkg.go.dev/github.com/savsgio/gotils@v0.0.0-20230208104028-c358bd845dee since i don't have the other code that is causing your error, you have to find it by narrowing it down

[schooltech]

thank you @ReneWerner87 , I found that when importing both the websocket and session libraries, I get a conflict error with the following code: `package main

import ( "github.com/gofiber/contrib/websocket" "github.com/gofiber/fiber/v2" "github.com/gofiber/fiber/v2/middleware/cache" "github.com/gofiber/session/v2" "github.com/gofiber/session/v2/provider/redis" "strings" "time" )

var Session *session.Session

func SetupWebsocket(app fiber.App) { app.Use(cache.New(cache.Config{ Next: func(c fiber.Ctx) bool { return strings.Contains(c.Route().Path, "/ws") }, }))

cfg := websocket.Config{
    RecoverHandler: func(conn *websocket.Conn) {
        if err := recover(); err != nil {
            conn.WriteJSON(fiber.Map{"customError": "error occurred"})
        }
    },
}

app.Get("/ws/:id", websocket.New(func(c *websocket.Conn) {}, cfg))

}

func SetupSession(app fiber.App) { provider, err := redis.New(redis.Config{ KeyPrefix: "verifyrest", Addr: "localhost:6379", PoolSize: 8, //nolint:gomnd IdleTimeout: 30 time.Second, //nolint:gomnd DB: 0, }) if err != nil { panic(err) }

Session = session.New(session.Config{
    Provider: provider,
})

}

func main() { app := fiber.New()

SetupWebsocket(app)
SetupSession(app)

app.Listen(":3000")

} `

github.com/gofiber/session/v2 is deprecated Pls use it from the core
