reproduction of getsentry/sentry-javascript#6077 (comment)
NOTE: the default port for reproduction is 5173
or
- pnpm i
- pnpm dev
When WITH_SENTRY in src/main.ts set to true, http://localhost:5173/ will display "download failed" with following error.
Access to fetch at 'http://localhost:3000/real-download-path' (redirected from 'http://localhost:5173/api/download') from origin 'http://localhost:5173' has been blocked by CORS policy: Request header field baggage is not allowed by Access-Control-Allow-Headers in preflight response.
By setting WITH_SENTRY to false, the error will be resolved.
