Solvedlighthouse ci Heroku server setup doesn't work

I'm having some trouble setting up a Heroku server according to the documentation.

I followed the instructions, but when I run heroku open, I'm getting an Application error from Heroku.

The logs look like this:

2020-12-29T13:07:20.658944+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=serene-caverns-NUMBER.herokuapp.com request_id=8e903a41-124c-433a-a440-f27e04eb8b3d fwd="220.100.124.32" dyno= connect= service= status=503 bytes= protocol=https
2020-12-29T13:07:21.002402+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=serene-caverns-NUMBER.herokuapp.com request_id=63de6f11-0bb6-4efc-af4b-1adf68cdb001 fwd="220.100.124.32" dyno= connect= service= status=503 bytes= protocol=https

I then tried to update LHCI following the instructions.

When I did that, I realized that following the docs commits the node_modules directory when updating, but node_modules is not committed in the initial setup. Is that correct? (I have never used Heroku before, but it seems like either I should commit node_modules from the start, or never commit it.

Next I tried to debug the app myself:

heroku run bash
npm start

This gave me the following error:

Starting server...

(node:24) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:24) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

This error message and this Stack Overflow question suggest the problem is related to SSL, but I don't know how to fix it. Any help would be much appreciated.

And if necessary, here is the build log when I updated the app:

✔️Accepted Answer

@anton-karlovskiy thanks for the code! If you change it to

createServer({
  port: process.env.PORT,
  storage: {
    storageMethod: 'sql',
    sqlDialect: 'postgres',
    sqlConnectionSsl: true,
    sqlConnectionUrl: process.env.DATABASE_URL,
    sqlDialectOptions: {ssl: true}, // note this new line
  },
})

does it work?

Other Answers:

@radzivil @Matsyashchik are you using node 12 in your Heroku worker? It should be the default according to their documentation and our uses of it, but apparently it seems like that's randomly not the case.

If the below fixes the issue

--- a/package.json
+++ b/package.json
@@ -6,5 +6,8 @@
     "@lhci/server": "0.7.x",
     "pg": "^7.12.1",
     "pg-hstore": "^2.3.3"
+  },
+  "engines": {
+    "node": "12.x"
   }
 }

We'll add that to our docs too.
