panic: error parsing uri: scheme must be "mongodb" or "mongodb+srv" Golang - MongoDB connection error

This is the error I am getting when I docker-compose up my app in docker-desktop.

{ { }}  panic: error parsing uri: scheme must be "mongodb" or "mongodb+srv"  goroutine 1 [running]:  go-products/database.ConnectDB(0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0)  /app/database/database.go:15 +0x145  main.main()  /app/main.go:14 +0x13d    

Here is my main.go file

package main    import (      "fmt"      "github.com/gorilla/mux"      "go-products/config"      "go-products/database"      "net/http"  )    func main() {      conf := config.GetConfig()      fmt.Println(conf)      db := database.ConnectDB(conf.Mongo)      fmt.Println(db)      r := mux.NewRouter()      http.ListenAndServe(":8080", r)  }  

This is the database file where I try to make connection.

package database    import (      "context"      "go-products/config"      "go.mongodb.org/mongo-driver/mongo"      "go.mongodb.org/mongo-driver/mongo/options"  )    func ConnectDB(conf config.MongoConfiguration) *mongo.Database {      connection := options.Client().ApplyURI(conf.Server)      client, err := mongo.Connect(context.TODO(), connection)        if err != nil {          panic(err)      }        return client.Database(conf.Database)  }  

config.go file

package config    import "github.com/spf13/viper"    type Configuration struct {      Environment string      Mongo       MongoConfiguration  }    type MongoConfiguration struct {      Server string      Database string      Collection string  }    func GetConfig() Configuration {      conf := Configuration{}      viper.SetConfigName("config")      viper.SetConfigType("yml")      viper.AddConfigPath("./config")        err := viper.ReadInConfig()      if err != nil {          panic(err)      }        return conf  }  

this is config.yaml file.

environment: dev  mongo:    server: mongodb://mongo:27017    database: Mgo    collection: Products  

I have checked the official documentation and some resources but couldn't find a way to handle this in Golang environment. What should I change here?
