Answer 1

Add node version to your package.json: "engines": { "node": "v15.10.0" }
Change the "start" script from "nodemon server.js" to "node server.js". If you want to use nodemone locally, add one more script like : "dev": "nodemon server.js" and use npm run dev to start the server locally.
You must push your .env to your heroku server also.
Check if you .env file is being ignored in .gitignore.
ps: package.json: I don't see "nodemon" in your "dependencies".
did you installed it? If you installed it, it should be there like : "nodemon": "^2.0.7" or if you installed it with npm i --save-dev: "devDependencies": { "nodemon": "^2.0.7" }
Wish this help you.
