Ah yeah we are missing this in our Heroku guide.

In your server.js (production: ./config/env/production/server.js)

You need to set the url key from here: https://strapi.io/documentation/v3.x/concepts/configurations.html#server to your Heroku app URL

In your ./config/env/production/server.js it should look something like:

module.exports = ({ env }) => ({
    host: env("HOST", "0.0.0.0"),
    port: env.int("PORT", 1337),
    url: env("APP_URL"),
    admin: {
      auth: {
        secret: env('ADMIN_JWT_SECRET'),
      },
    },
  });

Then you can set the APP_URL environment variable in heroku with their CLI:

heroku config:set HEROKU_URL=$(heroku info -s | grep web_url | cut -d= -f2)

Which will be something like: http://myapp.herokuapp.com

Quick side point as I see there might some confusion as to what the env() function does in those files. I’d suggest you take a look at this: https://strapi.io/documentation/v3.x/concepts/configurations.html#casting-environment-variables

The env() function has two parameters, the first is the name of the environment variable process.env.SOME_VAR such as env('SOME_VAR') and if that process.env.SOME_VAR is undefined you pass an alternative.

So env('SOME_VAR', 'defaultValue') will read and use process.env.SOME_VAR if it exists, if it’s undefined then it will use defaultValue instead. There is no need to define the process.env.SOME_VAR manually, and if you don’t want a default value then you only need: env('SOME_VAR')
