`plugin-react`: Fails to bundle `@sentry/react` if `mode` is not `production`

Describe the bug

I am using Vite in a project using @sentry/react, and when I vite build the project with a --mode other than production it fails with the message seen in the Logs section.

I’ve tried to use the exclude option to exclude /node_modules/ and various other paths but they did not make a difference.

This only happens with plugin-react included and using jsxRuntime: 'automatic'

Had the same problem. Solved by adding NODE_ENV=production to .env.staging file.

// package.json
{
  // ...
   "scripts": {
     // ...
     "build:staging": "NODE_ENV=production tsc && vite build --mode staging",
     // ...
   },
   // ...
}

# .env.staging
NODE_ENV=production
VITE_APP_TITLE=My App (staging)

I think it can be simplified by just adding this.

"build:staging": "tsc && NODE_ENV=production vite build --mode staging",

Had the same problem. What helps is to set the environment variables NODE_ENV=production, e.g., with cross-env in your package.json script build:

// package.json
{
  // ...
   "scripts": {
     // ...
     "build": "cross-env NODE_ENV=production tsc && vite build",
     // ...
   },
   // ...
}

I also think the mode should not alter the PROD environment variable in Vite, i.e., sometimes not making a production build.
