Gatsby build fails when run locally without SENTRY_AUTH_TOKEN

[abemedia]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using? If you use the CDN bundles, please specify the exact bundle (e.g. bundle.tracing.min.js) in your SDK setup.

@sentry/gatsby

SDK Version

7.47.0

Framework Version

gatsby ^5.8.1, react 18.2.0

Link to Sentry event

No response

SDK Setup

Sentry.init({
  dsn: 'my_dsn',
  release: 'my_release',
  environment: 'my_environment',
})

Steps to Reproduce

Run gatsby build (without setting SENTRY_AUTH_TOKEN) on my local machine.

Expected Result

The site builds, skipping the upload of sitemaps or creation of release (this works fine on my CI).

Actual Result

Fails the build with the following error message:

failed Building production JavaScript and CSS bundles - 25.753s

 ERROR #98123  WEBPACK.BUILD-JAVASCRIPT

Generating JavaScript bundles failed

Sentry CLI Plugin: Command failed: /home/adam/Work/optimus/optimusmine.com/node_modules/@sentry/cli/sentry-cli releases new 5ef49904f28dae3baa2d66773a83443f2df58cef

  caused by: sentry reported an error: Authentication credentials were not provided. (http status: 401)

Add --log-level=[info|debug] or export SENTRY_LOG_LEVEL=[info|debug] to see more output.
Please attach the full debug log to all bug reports.

Not sure why this is happening locally but not on GitHub Actions but a simple fix might be to handle that error in https://github.com/getsentry/sentry-javascript/blob/develop/packages/gatsby/gatsby-node.js#L48-L54

Hi @abemedia thanks for writing in!

I reproduced this problem with a simple Gatsby test app and overall, I think you're right. We shouldn't crash your build because an auth token is missing. I'll open a PR with a fix. Also, on that note, thanks for pointing out the line, you're spot on!

However, just to clarify some things:

To get to this error, you have to set SENTRY_ORG and SENTRY_PROJECT env variables. So you could assume that people actually want to upload source maps but missed to set an auth token. Therefore, I believe, we should print a warning in this case.

Two possibilities: Either because NODE_ENV !== 'production' or because the two variables above were not set.
