I already try some solution in another forum but not solved
This is my package json
"scripts": {
"start": "node server.js --production",
"heroku-postbuild": "npm run build",
"test": "node ace test",
"dev": "node server.js",
"build": "next build ./next",
"export": "next export ./next"
},
I already look in another but maybe not same implement with my project, any solution?

Answer 1

Do you have the ENV_SILENT parameter in the heroku variables?
Have a nice day

Answer 2

If .env file is missing, AdonisJs throws an exception by default. However, you turn off the exception as follows
somewhere in your code, you are trying to open the .env file. so generate an error.
You can disable .env file and directly use your system environment variables visit this page for more information
