How do I troubleshoot dotenv issues in my application?

I'm having trouble loading my .env file in my Node.js application. What should I check?

First, ensure that your .env file is in the root directory of your project. Also, check if you have the dotenv package installed and required in your code.

I have the dotenv package installed, but it's still not working. What else could be wrong?

Make sure you're calling require('dotenv').config() at the very top of your main file. Also, check for typos in your .env file.

I checked everything, and it still doesn't work. Could it be a permissions issue?

Yes, it's possible. Ensure that your application has permission to read the .env file. You can check the file permissions in your terminal.
