Heroku Nodejs - React error deploying app

Question

Hi everyone I'm trying to deploy a React-node App on Heroku and this is the console log of heroku:

-----> Building on the Heroku-20 stack
-----> Determining which buildpack to use for this app
-----> Node.js app detected

       We're sorry this build is failing! You can troubleshoot common issues here:

       Some possible problems:

       Love,

I had similar issue. Deleting package-lock.json file solved the issue.

I have solved this issue when i figured out that my local npm version wasn't fit with the npm version in Heroku. I needed to add the same npm version in my Heroku environment as my local version like this in package.json:

{
"engines":{
"node":"yournodeversion",
"npm":"yournpmversion"
}
}

Using the create-react-app buildpack for Heroku can solve this issue.

Currently, your react-app is treated as a regular node.js application as the node.js buildpack is used which is automatically inferred due to the presence of package.json in the root.
