I have deployed my app from git to Heroku successfully and I enabled automatic deployment that worked fine. Somewhere in the past 2 weeks the deployment has started failing each time for the same reason, even though there's no problem with the code in the git - it's running fine.
You can see in the log file that it mentions each time:
" Creating an optimized production build...
Failed to compile.
./src/App.js
Cannot find file './pages/MainPage' in './src'.
But the MainPage file is right where it should be and the app is compiling and running locally.
I've tried disconnecting and reconnecting from git and heroku,
I've deleted and re-installed the node modules and the package-lock,
and I cache clean --force
.
I don't know what went wrong, any suggestions?
Thank you!

Your production build may be referencing a relative import that for some reason does not exist. Reconfigure that import using ${__dirname}/path_to_file
and try again.
Here is a link of how to use it.
Hope this works for you.
