Trouble deploying to DO’s app platform

  Typically, any platform's health check would be pinging the application to see if it received a good HTTP response. If it is a good response, it would be considered healthy.

  It sounds like DO's health checks are failing, so it is likely trying to restart your application. I'd check out their health check documentation here to see how it's configured. It looks like it checks on port 8080 as default - it should match your application port.

  These links look relevant:

  You can customize the http health check endpoint in DO. It is common to a route to your express app for your check. Here is an eample of a server that adds a check on GET /health:

  // server.ts
  import express from 'express';
  import payload from 'payload';
  import dotenv from 'dotenv';
  
  dotenv.config();
  
  const server = express();
  
  payload.init({
    secret: process.env.PAYLOAD_SECRET,
    mongoURL: process.env.MONGO_URL,
    express: server,
  });
  
  // health check
  server.get('/health', (req, res) => {
    res.send('ok');
  });
  
  server.listen(process.env.PORT, async () => {
    console.log(`Server listening on ${process.env.PORT}...`);
  });

  Yep saw those links! Pretty sure I have everything I should set to 8080. Added the /health route, no luck there either. Any ideas? These are the last couple of lines from the console before the health check error:

  [payload] [2022-12-06 14:26:44] yarn run v1.22.19
  [payload] [2022-12-06 14:26:44] $ cross-env NODE_ENV=production node dist/index.js
