App not opening after heroku deployment

General
1

Hi

I just uploaded my first strapi app in heroku. But its not opening and showing some crash report.

My doubt is this two file server.js and database.js

module.exports = ({ env }) => ({

  host: env('HOST', '0.0.0.0'),

  port: env.int('PORT', 1337),

  url: env('MY_HEROKU_URL'),

  app: {

    keys: env.array('APP_KEYS'),

  },

});

const parse = require('pg-connection-string').parse;

const config = parse(process.env.DATABASE_URL);

module.exports = ({ env }) => ({

  connection: {

    client: 'postgres',

    connection: {

      host: config.host,

      port: config.port,

      database: config.database,

      user: config.user,

      password: config.password,

      ssl: {

        rejectUnauthorized: false

      },

    },

    debug: false,

  },

});

its fixed with this in server.js

module.exports = ({ env }) => ({

    url: env("MY_HEROKU_URL"),

    proxy: true,

    app: {

      keys: env.array("APP_KEYS",['keys','keys']
},

  });
