Can you show an example of your vite config? I do not think vite loads .env during buildtime in your vite config, it only injects it to your import.meta.env in your app code.

You can verify if the env is defined during vite build time by console logging it and see if it has a value or not. Alternatively you can create a .env.sentry-build-plugin and put the auth token there, which does get read automatically by our vite plugin unlike plain .env.

I thought process.env is also okay during build 🤔
