[AntigravityInstalledVersionBadge] failed to load installed…

Error message

[AntigravityInstalledVersionBadge] failed to load installed version:

What it means

The badge's `loadVersion` calls the Tauri command behind `getAntigravityInstalledVersionInfo(runtimeTarget, 'quick')` to read the locally installed Antigravity version. A rejection (command error, IPC failure, or filesystem/read error on the install metadata) is caught and logged, and the badge resets its info to null.

Solutions

Verify Antigravity is installed at the expected path and the version metadata file exists and parses.
Check the runtimeTarget argument matches a supported target in the backend command.
Inspect the logged `error` object for the underlying Tauri command rejection reason and fix that command's failure (permissions, path).
Add a fallback UI state (e.g. 'unknown version') instead of silently hiding the badge.

Example fix

null

Defensive patterns

Strategy: fallback

Validate before calling

const info = await safeGetInfo();
async function safeGetInfo() {
  try { return await getAntigravityInstalledVersionInfo(runtimeTarget, 'quick'); }
  catch { return null; }
}

Type guard

function hasVersionInfo(v: unknown): v is { version: string } {
  return typeof v === 'object' && v !== null && 'version' in v && typeof (v as any).version === 'string';
}

Try / catch

try {
  const info = await getAntigravityInstalledVersionInfo(runtimeTarget, 'quick');
  setInfo(info ?? null);
} catch {
  setInfo(null); // render 'version unknown' placeholder
}

Prevention

Render an 'unknown version' placeholder rather than hiding the badge silently
Validate install path existence before invoking the scan
Keep runtimeTarget values in a shared constant to avoid typos

When it happens

Trigger: The `quick` version scan throws: the Antigravity install directory is missing or unreadable, the version file is malformed, the Tauri command rejects, or the component's runtimeTarget does not match any installed build.

Common situations: Antigravity not installed or partially uninstalled; permission-restricted install path; version manifest format changed after an app update; calling with the wrong runtimeTarget value.
