Where a failed sign-in lands

GET
/auth/error
curl --request GET \
--url https://api.pealboard.com/auth/error \
--header 'Authorization: Bearer <token>'

Better Auth redirects a failed sign-in here with ?error=<code>, and this hands the browser to the workspace application’s sign-in screen with the same code.

It exists on this side because the application’s Worker proxies /auth/* to this API unchanged — which is what makes the session cookie belong to the origin the person is looking at, and which means no route in the SPA can answer this path. Without it a failed sign-in ends on the library’s own unbranded page.

Access. No credential. Open to any caller. A sign-in has just failed, so by definition there is no credential. It reads one query parameter and answers with a redirect; it touches nothing.

error
string

A redirect to the application’s sign-in screen.

No valid credentials.
