Create Tanstack App

Describe the bug

The following error occurs on startup when including Sentry as an addon.

TypeError: Cannot read properties of undefined (reading 'VITE_SENTRY_DSN')
    at file:///Users/marcusheinonen/code/web/sentry-bug-example/instrument.server.mjs:3:24
    at ModuleJob.run (node:internal/modules/esm/module_job:327:25)
    at async onImport.tracePromise.__proto__ (node:internal/modules/esm/loader:663:26)
    at async asyncRunEntryPointWithESMLoader (node:internal/modules/run_main:94:9)

I believe this line needs to be updated to use process.env.VITE_SENTRY_DSN instead.
