I have a go API setup using Serverless. In my root directory I have main.go and .env, as well as a config folder which contains config.go. I’m having issues as my attempts to access the endpoint throws a runtime error due to it being unable to access the environment variables once deployed (works fine locally).

When I deploy to AWS, and test out the endpoint I get: Failed to load env file: open ./.env: no such file or directory. How do I fix this issue?

Within config.go I have:

package config


import (
    "fmt"
    "log"
    "os"

    "github.com/joho/godotenv"
)

func config(key string) string {
  if err := godotenv.Load("./.env"); err != nil {
    log.Fatalf("Failed to load env file: %v", err)
  }
  return os.Getenv(key)
}

This function is used, for example, to get the database connection string when setting up my DB connection.

My serverless.yml is:

service: my_service

  name: aws
