Common Errors (& Fixes) In Web Application Deployment With Heroku

Check my table of Common Errors (& Fix) when trying to deploy with Heroku.

This time when I tried to deploy my $impleTrade web app in Heroku, I got some new errors that I didn’t get previously. It took me a while to search for answers from Stackoverflow.

While the answers were very helpful, they were more like bread scrums. So, I think it is useful for me and others if I create a summary of errors and my fixes. I will try to keep this table updated as I go.

The most common error is H14 — No web dynos running. While most popular answers were to check Procfile if you declare process type with correct syntax. I found out the causes were more than that.

Check my table here to see Errors, What do they mean, The causes, and Fixes.

If you encountered other errors, please comment so I can add them to my list.

Thank you!
