console: copied invitation link is unusable — buildAcceptUrl rebuilds the trailing-dot host that resolveHomeUrl already retired #4472

Moved from objectstack-ai/objectstack#8090 at triage (file-at-destination: the fix is entirely in this repo). Filed 2026-08-12 by @baozhoutao from a multi-org console walkthrough, original grading priority:p1. Batch siblings: objectstack-ai/objectstack#8091 #8092 #8093 #8094 (see that thread).

Copying an invitation link from the workspace Invitations tab yields a URL that cannot be opened. The recipient of an invitation therefore has no working way in.

Repro

1. Multi-org runtime, zh console, sign up and create a workspace (owner).
2. Users → Invite user → invite lisi@acme-test.com as member.
3. Workspace switcher → Manage members → Invitations tab → click Copy invitation link.
4. Paste the clipboard content.

Actual

http://localhost:8080./accept-invitation/bgn1XAfRuCQUS1l9NBqOMGgJDUYm5l56

Two defects in one string:

• trailing-dot host — localhost:8080. (the port is followed by .);
• the console mount is missing — the console is served under /_console/, and GET /accept-invitation/ (dot removed) is answered by the server with {"error":"Not found"}.

The only URL that renders the accept page is http://localhost:8080/_console/accept-invitation/<id> — verified working, the page loads and the invitation can be accepted.

Expected

The copied link is the one the recipient can open: <console mount>accept-invitation/<id>.

Cause

buildAcceptUrl rebuilds the URL from import.meta.env.BASE_URL, which is '.' in a portable (base: './') build:

// packages/app-shell/src/console/organizations/manage/InvitationsPage.tsx:32
function buildAcceptUrl(invitationId: string): string {
  const base = (import.meta as any).env?.BASE_URL ?? '/';
  const normalized = base.endsWith('/') ? base : `${base}/`;
  return `${window.location.origin}${normalized}accept-invitation/${invitationId}`;
}

Duplicated verbatim in packages/app-shell/src/console/organizations/manage/InviteMemberDialog.tsx:39 (the "share link" view of the invite dialog), so the freshly-created-invitation link is broken the same way.

This is the exact failure mode resolveHomeUrl.ts was written to retire — its header documents it:

${origin}${import.meta.env.BASE_URL}home broke portable builds (base: './'), producing https://host./home — trailing-dot host.

Suggested fix

Drop both local buildAcceptUrl copies and call the existing mount-aware helper:

import { resolveConsoleUrl } from '../resolveHomeUrl';
const url = resolveConsoleUrl(`accept-invitation/${invitationId}`);

resolveConsoleUrl resolves against the deployment mount, which is what both WorkspaceSwitcher and OrganizationsPage already use for full-page navigations. A regression test asserting the copied URL contains no :. and starts with the console mount would pin it.

Environment

Local dev server http://localhost:8080, multi-org enabled, zh locale, observed 2026-08-12. The server was started by the maintainer and its exact commit is not verified; the source quoted above is the objectui main checkout at filing time.
