Next.js: Source maps info don't show in with-sentry example

[yantakus]

Cloned with-sentry example, provided DSN, as described in readme. Built the app in production mode, raised an exception. Result - error stack traces point to uglified files:

As I see in the code, it should provide source maps to sentry.

Any additional configuration needed to set up source maps? Or it's just a bug?

Sentry will try to fetch the sourcemaps relatively to your hosted scripts. There are common pitfalls:

• You use a different domain e.g CDN to host your files
• You didn't enable the token mechanism
• On SSR it can't work because nodejs doesn't respect sourcemaps
• Sentry can't fetch the files in development localhost
• You can inline your sourcemaps but this is not ideal since it expose your source code.

As a solution you can upload your source maps to sentry.

I've tried uploading the source maps to sentry but it actually didn't work, could you give an example on how to upload the files to sentry?
