nextjs process.env undefined

  1. Ensure that the environment variable is defined in your Next.js project by checking the .env file or any other configuration file where environment variables are declared.

  2. Confirm that the environment variable is prefixed with "NEXT_PUBLIC_" if you intend to use it in the client-side code, as Next.js requires a prefix for public variables.

  3. Restart your development server or redeploy your application to make sure that changes to the environment variables take effect.

  4. Verify the correct usage of process.env in your code, ensuring that you are accessing it in the appropriate context (e.g., server-side or client-side).

  5. Check for any typos or naming discrepancies in the environment variable name when accessing it through process.env.

  6. If you are using a custom server, ensure that the environment variable is correctly loaded and accessible within the server script.

  7. Confirm that the environment variable is set in your production environment if the issue persists in a production build.

  8. If you are using a build tool or deployment platform, make sure that it correctly handles environment variables during the build and deployment process.

  9. Consider logging or debugging statements to trace the flow of the code and identify any issues related to the environment variable.

  10. If the problem persists, consult the Next.js documentation or community forums for specific troubleshooting tips related to environment variables in Next.js applications.
