…ACT-S)
The official `isTauri()` from `@tauri-apps/api/core` reads
`globalThis.isTauri`, which Tauri's CEF bootstrap sets early — but
`__TAURI_INTERNALS__` (and the `postMessage` bridge it dispatches
through) is injected *after* `on_after_created` fires. An `invoke()`
landing in that gap throws
TypeError: Cannot read properties of undefined (reading 'postMessage')
deep inside `@tauri-apps/api`'s `sendIpcMessage` (see Sentry
OPENHUMAN-REACT-S). The error escapes the local try/catch because it's
synchronously thrown inside a `new Promise(...)` body and lands as an
unhandled rejection / Sentry event.
Strengthen the centralised `isTauri()` wrapper in
`app/src/utils/tauriCommands/common.ts` so it additionally checks that
`window.__TAURI_INTERNALS__.invoke` is a function before claiming the
runtime is ready. Migrate every production call site that previously
imported `isTauri` from `@tauri-apps/api/core` to import from this
hardened wrapper instead.
The hardened wrapper is purely additive — it returns `false` only when
the underlying primitive *also* returns `false`, OR when the IPC
handle isn't actually present. Callers that gate on `isTauri()` BEFORE
invoking therefore take the non-Tauri branch during the bootstrap gap
(skip / fallback / try-the-web-path), not the throwing branch.
Files updated to use the hardened wrapper:
- app/src/components/BootCheckGate/BootCheckGate.tsx
- app/src/components/settings/panels/DeveloperOptionsPanel.tsx
- app/src/lib/nativeNotifications/tauriBridge.ts
- app/src/lib/webviewNotifications/service.ts
- app/src/main.tsx
- app/src/services/backendUrl.ts
- app/src/services/coreRpcClient.ts
- app/src/services/meetCallService.ts
- app/src/services/webviewAccountService.ts
- app/src/utils/desktopDeepLinkListener.ts
- app/src/utils/oauthAppVersionGate.ts
- app/src/utils/openUrl.ts
Test infra:
- app/src/test/setup.ts seeds `window.__TAURI_INTERNALS__` so existing
test mocks of the underlying `isTauri()` continue to take the Tauri
branch; tests that *want* to exercise the bootstrap-gap behaviour
can `delete window.__TAURI_INTERNALS__` in a `beforeEach`.
- app/src/utils/openUrl.test.ts updates its mock path to match the
new import.
Remaining `@tauri-apps/api/core::isTauri` imports are in test files
that mock the underlying primitive directly — the hardened wrapper
reads from that primitive so the mocks continue to drive behaviour.

Review — fix(ipc): guard isTauri() on TAURI_INTERNALS.invoke
Overall this is a clean, well-scoped fix for a real production crash (OPENHUMAN-REACT-S). The hardened wrapper is strictly additive, the migration is mechanically complete, and the test suite directly reproduces the gap scenario. A few inline notes below — nothing blocking.
Verified / looks good:
- Wrapper only returns
falsewhereinvoke()would have thrown anyway - Barrel re-export (
tauriCommands/index.ts) means files importing via barrel auto-inherit the fix webviewAccountService.tsre-export coversOpenhumanLinkModal.tsx- Test case #3 directly reproduces OPENHUMAN-REACT-S
- No dynamic imports, no
import.meta.envmisuse, no CEF JS injection - All relevant CI checks pass
| // regress to the non-Tauri path. Seed a no-op handle once globally so the | ||
| // IPC-readiness check passes by default. Tests that *want* the CEF gap | ||
| // behaviour can `delete window.__TAURI_INTERNALS__` in a `beforeEach`. | ||

[major] __TAURI_INTERNALS__ seed is not reset between tests.
The seed is set once globally at module load but not restored in afterEach. Tests that delete window.__TAURI_INTERNALS__ (as the comment suggests) could contaminate subsequent tests sharing the same jsdom worker if they don't individually restore it. common.test.ts handles this correctly with its own save/restore, but any other test file that deletes the global without restoring it will silently cause subsequent tests to take the non-Tauri branch.
Suggestion — re-seed in the existing afterEach:
afterEach(() => {
clearRequestLog();
cleanup();
// Re-seed the IPC handle after any test that may have deleted it.
(window as unknown as { __TAURI_INTERNALS__: { invoke: () => Promise<unknown> } })
.__TAURI_INTERNALS__ = { invoke: vi.fn(() => Promise.resolve()) };
});There was a problem hiding this comment.
Re-seeded window.__TAURI_INTERNALS__ inside the existing afterEach in app/src/test/setup.ts so tests that delete the handle can't contaminate sibling tests in the same jsdom worker. Landed in 169f1fc.

[minor] No debug logging when the guard short-circuits due to missing IPC bridge.
Per CLAUDE.md's debug logging requirement, new/changed flows should log branches and state transitions. This wrapper is the single choke point for catching the CEF gap at runtime — but when it returns false due to a missing IPC bridge (not just !coreIsTauri()), there's no log entry. A lightweight debug log on the bridge-missing branch would make the fix observable in dev with zero production overhead:
import debug from 'debug';
const log = debug('tauri:ipc-guard');
export const isTauri = (): boolean => {
if (!coreIsTauri()) return false;
if (typeof window === 'undefined') return false;
const internals = (window as unknown as { __TAURI_INTERNALS__?: { invoke?: unknown } })
.__TAURI_INTERNALS__;
if (typeof internals?.invoke !== 'function') {
log('isTauri() → false: IPC bridge not yet wired (CEF gap or non-Tauri)');
return false;
}
return true;
};There was a problem hiding this comment.
Added debug('tauri:ipc-guard') logging in app/src/utils/tauriCommands/common.ts on the branch where internals?.invoke isn't a function, making the CEF bootstrap gap observable in dev with zero prod overhead. Landed in 169f1fc.

[minor] Stale comment about "pre-Tauri detection".
The existing comment near the currentWindowLabel block says something like "Detect it before we touch any Tauri APIs" — but tauriRuntimeAvailable() now IS the hardened isTauri() which itself reads window.__TAURI_INTERNALS__. Worth a quick update to reflect reality so a future engineer doesn't wonder why we're touching internals in the "pre-Tauri" detection block. Behavior is correct; just the comment is misleading.
There was a problem hiding this comment.
Rewrote the stale comment block above the urlWindowParam IIFE in app/src/main.tsx to reflect that tauriRuntimeAvailable() is the hardened isTauri() which itself reads window.__TAURI_INTERNALS__. Landed in 169f1fc.
- test/setup.ts: re-seed window.__TAURI_INTERNALS__ in afterEach so
tests that delete it can't contaminate sibling tests in the same
jsdom worker.
- utils/tauriCommands/common.ts: log via debug('tauri:ipc-guard')
when isTauri() short-circuits on a missing IPC bridge so the CEF
bootstrap gap is observable in dev (zero prod overhead).
- main.tsx: refresh stale "pre-Tauri detection" comment near the
urlWindowParam block; tauriRuntimeAvailable() is the hardened
isTauri() and itself reads window.__TAURI_INTERNALS__.

Migrate every production call site to import from this hardened wrapper instead of from@tauri-apps/api/coredirectly. During the CEF bootstrap gap the wrapper now returnsfalse, so every existingif (!isTauri()) return;site takes the non-Tauri fallback branch instead of throwing into the runtime.Problem

The throw happens synchronously inside anew Promise(executor)body, so the local synchronous try/catch around theinvoke()call doesn't catch it — the rejection escapes the call site entirely and lands as a global Sentry event.The codebase's canonical guard pattern (

Single point of leverage: the centralised wrapper in
