Why Is My Netlify Build Failing After Adding a New Environment Variable?

Hi everyone,

I’ve been loving how easy it is to deploy sites with Netlify, but I recently hit a snag and could use some guidance. Here’s the issue:

I added a new environment variable in my Netlify dashboard (under Site Settings → Environment Variables) to store an API key for a third-party service. Since then, my builds have started failing with the following error:

csharp

Copy code

[Error] Process exited with code 1  
Environment variable [MY_ENV_VARIABLE] is undefined.

Here’s what I’ve tried so far:

  1. Verified the environment variable spelling (checked multiple times).
  2. Ensured the variable is being accessed in my code using process.env.MY_ENV_VARIABLE.
  3. Cleared the Netlify cache and retriggered the build.
  4. Double-checked that the variable is marked as required in my build setup.

Despite these steps, the problem persists. Has anyone encountered a similar issue or have any idea what might be causing this?

I’d appreciate any tips or troubleshooting steps you could share. Also, if there’s a best practice for managing environment variables with Netlify, I’d love to learn more.

What’s the site name?
