authToken from nuxt.config.ts not read during Docker build - source maps not uploaded #19098
Description
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/nuxt
SDK Version
10.38.0
Framework Version
Nuxt 4.1.3, Vue 3.5.22
Link to Sentry event
N/A (source maps not uploaded)
Reproduction Example/SDK Setup
nuxt.config.ts:
modules: ['@sentry/nuxt/module'],
sourcemap: {
client: 'hidden',
server: false,
},
sentry: {
org: 'my-org',
project: 'my-project',
authToken: process.env.SENTRY_AUTH_TOKEN,
sourcemaps: {
filesToDeleteAfterUpload: [
'.output/**/*.map',
'.output/public/**/*.map',
],
},
},
})```
sentry.client.config.ts:
```import * as Sentry from "@sentry/nuxt";
Sentry.init({
dsn: "https://xxx@xxx.ingest.us.sentry.io/xxx",
tracesSampleRate: 1.0,
enableLogs: true,
sendDefaultPii: true,
debug: false,
});```
### Steps to Reproduce
1. Set up a Nuxt 4 project with @sentry/nuxt module
2. Configure authToken: process.env.SENTRY_AUTH_TOKEN in nuxt.config.ts under sentry options
3. Build inside a Docker container with SENTRY_AUTH_TOKEN passed as a build argument:
ARG SENTRY_AUTH_TOKEN
ENV SENTRY_AUTH_TOKEN=$SENTRY_AUTH_TOKEN
RUN pnpm build
4. Verify the env var is available: echo $SENTRY_AUTH_TOKEN shows the correct value inside the container
5. Run pnpm build
6. After the container run, if i make echo $SENTRY_AUTH_TOKEN, the token is correctly display.
### Expected Result
The Sentry Rollup plugin should read the authToken from nuxt.config.ts (which references process.env.SENTRY_AUTH_TOKEN) and upload source maps to Sentry.
### Actual Result
Build outputs this warning and source maps are not uploaded:
[sentry-rollup-plugin] Warning: No auth token provided. Will not upload source maps.
Please set the `authToken` option. You can find information on how to generate a
Sentry auth token here: https://docs.sentry.io/api/auth/
The environment variable SENTRY_AUTH_TOKEN is confirmed to be set and accessible during the build process, but the plugin does not pick it up from the config.
### Additional Context
- Deployment platform: Dokploy (Docker-based)
- Build system: Dockerfile
- The same config works when running pnpm build locally with the env var exported
- Tried both SENTRY_AUTH_TOKEN and NUXT_SENTRY_AUTH_TOKEN variable names
- Also tried omitting authToken from config entirely (relying on auto-detection of SENTRY_AUTH_TOKEN) - same result
