Discussion on: Hosting an App with Heroku and Netlify (if you've never done it before)

Hi Jeff - Did you check what your log said, the one mentioned in that error message? What's it telling you?

[Jeff Chavez]

I tried to correct the error on the port and updated it and this is now what I got on the logs:

Hi, thanks for the reply. Here's what I got:

dev-to-uploads.s3.amazonaws.com/i/...

So your project might vary - my server project doesn't have a start command that Heroku deals with. It just needs access to the GitHub repo.

This error looks like it can't find a start command. That'll be in your package.json file if it exists. If it's there, you might try running npm run start - the run command is necessary for most npm scripts, though sometimes start will work without it.

Hope that helps! From your other comment, it looks like your build succeeded, so hopefully you're able to move forward!

[Jeff Chavez]

Cool! I'll try that

[Jeff Chavez]

Still not working. Hmmm.

[Linda Thompson]

Sorry I can't be of more help! Keep searching and troubleshooting, I'm sure you'll get it figured out!

[Jeff Chavez]

Thank you so much!
