`sentrySvelteKit` loads Vite config in the wrong mode #15414

giacomoran · 2025-02-14T13:10:39Z

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?

@sentry/sveltekit

SDK Version

9.1.0

Framework Version

2.16.0

Link to Sentry event

No response

Reproduction Example/SDK Setup

https://github.com/giacomoran/sveltekit-sentry-vite-config

Steps to Reproduce

Create SvelteKit project
Add @sentry/sveltekit as dependency
Add the sentrySvelteKit plugin to Vite config
Log the mode in which the Vite config is loaded
Run vite build --mode staging

Expected Result

Every time the Vite config is loaded, the mode is staging.

Actual Result

When the sentrySvelteKit plugin loads the Vite config, the mode is production instead of staging.

Example output:

❯ bun vite build --mode staging

Hi @giacomoran thanks for reporting! Hmm yeah this looks like a consequence of #14886 (damn, never thought this change would be so problematic). We need to check if we can detect the mode dynamically. Otherwise I'm afraid we need to re-think our approach. I'll take a look.

Lms24 · 2025-02-18T16:36:14Z

Quick update: We decided to rework the source map setting extraction logic to use Vite's provided config hook instead of calling loadConfigFromFile. This however, requires a change in our bundler plugins so that we can pass in an option as a promise. I already opened

feat(core): Accept and await a promise in sourcemaps.filesToDeleteAfterUpload sentry-javascript-bundler-plugins#677 to make the change in our core (vite) plugin
fix(sveltekit): Avoid loading vite config to determine source maps setting #15440 which removes the loadConfigFromFile call from the SvelteKit plugin

This should be released in the next days.
