How to use lambda mountCode: true with Golang?

[jagonzalr]

Hello I'm trying to run Golang with localstack and mountCode: true

But I just get the error

FileNotFoundError: [Errno 2] No such file or directory: '/Users/jagonzalr/Development/dummy/src/hello'

serverless.yml

service: 'dummy'

package.json

"scripts": {    
    "deploy:local": "serverless deploy --stage local",
    "start":  "npm run deploy:local && npm run watch",
    "watch":  "nodemon --watch src -e go,js --exec npm run deploy:local"
  },

Go code
src/hello/main.go

func main() {
	handler := handler.Create()
	lambda.Start(handler.Run)
}

Update

I missed adding the code location inside volumes in docker-compose.yml

But now I got another issue: when I try to run the lambda function from the provided endpoint url I get in the console
Error: fork/exec path/src/hello: permission denied

Found my issue, I was pointing to the Go code instead of the compiled binary, once that was done everything works.
