I'm pretty new to fullstack development and have been trying to upload my site on heroku, I get this error message and I'm guessing it has something to do with my package-lock.json file in the root folder.
I have both front end and back end folders under one parent folder. Here is the link to the small project if you can check it out: https://github.com/manuelmort/tft-project
I usually upload some small sites to gh-pages but since they dont support server side code I have to use heroku. It builds succesfully but the site never starts because of the error message below on heroku CLI
