CodePudding user response：
you don't provide enought information for us to be able to help you, nobody can or will debug it for you in that regard.
Here, sharing your package.json and the entry file of your application would be useful!
Anyway it seems that npm run start is crashing, you could start by making sure that whatever command is run by npm run start is accessible in heroku (You might use a global dependencies that you have installed on your local machine which heroku doesn't).
I'll be glad to help you more if you provide required code snippets for us to understand what's happening!
