sentry-cli sourcemaps upload returns 401 "Invalid org token" for EU-region orgs

[janonymus]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

1. Have a Sentry organization on the EU data region (de.sentry.io).

2. Create an Organization Auth Token

3. Configure the environment as documented:
   SENTRY_AUTH_TOKEN=
   SENTRY_URL=https://de.sentry.io
   SENTRY_ORG=
   SENTRY_PROJECT=

4. Run a source-map upload, e.g.:
   sentry-cli sourcemaps upload --release ./dist

5. Observe the upload fail with:
   error: API request failed
   caused by: sentry reported an error: Invalid org token (http status: 401)

Expected Result

Expected:
sentry-cli uploads to de.sentry.io, the host given by SENTRY_URL

Actual Result

Actual:
401 Invalid org token. The EU organization token embeds sentry.io (the US host) inside the token, and sentry-cli trusts that embedded host over the explicit SENTRY_URL, so the request hits the wrong region and is rejected. There is no flag to override it.

My Workaround that i use now:
Using a Personal auth token instead of an Organization token; it honors SENTRY_URL and uploads to de.sentry.io correctly. (SENTRY_URL must remain set.)

Time wise this happend around:
