I have been recently attempting to deploy a simple golang app to heroku using the same method I used to deploy previous ones, and I'm running into error with my procfile execution.

I tried running both go build -o bin/main
and go build -o bin/main -v .
to build the binary file, but heroku is unable to build it for due to format error. How can I fix this? I'm running on a 64 bit window platform for reference.
Also, just in case, here is the code I am trying to deploy.
package main
import (
"fmt"
"log"
"net/http"
"os"
"strconv"
"github.com/go-chi/chi"
"github.com/go-chi/render"
"github.com/joho/godotenv"
)
type m map[string]interface{}
func main(){
godotenv.Load()
router := chi.NewRouter()
words := m{
"black": 10,
"red": 7,
"pink": 0,
"yellow": 5,
"blue": 9,
}
router.Get("/all", func(res http.ResponseWriter, req *http.Request) {
render.JSON(res, req, words)
})
router.Get("/add-color-rating/{color}/{rating}", func(res http.ResponseWriter, req *http.Request) {
color := chi.URLParam(req, "color")
rating, _ := strconv.Atoi(chi.URLParam(req, "rating"))
words[color] = rating
render.JSON(res, req, m{"added-rating": m{color: rating}})
})
fs := http.FileServer(http.Dir("./static"))
router.Handle("/static/*", http.StripPrefix("/static", fs))
fmt.Println("running on port:", os.Getenv("PORT"))
log.Fatal(http.ListenAndServe(os.Getenv("PORT"), router))
}
It could also be that you are trying to run an executable compiled for a specific architecture on a platform with a different architecture. Try specifying the the target os and architecture in which you expect to run the build as follows.
env GOOS=linux GOARCH=arm64 go build -o bin/main
