[ENHANCER] No app bundle found

Error message

[ENHANCER] No app bundle found

What it means

PatchAsar enumerates top-level .js files under _unpackedPath (resources/app.asar.unpacked) and filters via IsCandidateBundleFile, which accepts only index.js or files matching app-*.bundle.js. If nothing passes, there is no bundle to patch and the process aborts.

Solutions

1. Open resources/app.asar.unpacked and confirm it actually contains extracted files.
2. Verify AsarExtractor.ExtractAll completed without throwing (check [11]).
3. List the real bundle filenames; if Wand changed convention (no longer index.js / app-*.bundle.js), update IsCandidateBundleFile's constants (IndexBundleFileName / AppBundleFilePrefix / AppBundleFileSuffix).
4. If the dir is empty/corrupt, reinstall Wand to a known-good state, delete app.asar.backup + app.asar.unpacked.backup, and re-patch.

// Verify a candidate bundle exists before patching
var candidates = Directory.EnumerateFiles(_unpackedPath, "*.js", SearchOption.TopDirectoryOnly)
    .Where(f => f.EndsWith("index.js", StringComparison.OrdinalIgnoreCase)
             || (Path.GetFileName(f).StartsWith("app-", StringComparison.OrdinalIgnoreCase)
                 && Path.GetFileName(f).EndsWith(".bundle.js", StringComparison.OrdinalIgnoreCase)));
if (!candidates.Any())
    throw new InvalidOperationException("No candidate bundle in " + _unpackedPath + "; extraction may have failed.");

try { enhancer.Patch(); }
catch (Exception ex) when (ex.Message == "[ENHANCER] No app bundle found") {
    // inspect _unpackedPath, confirm extraction, then reinstall/re-extract
}

When it happens

Trigger: PatchAsar() at Enhancer.cs:124-131 after AsarExtractor.ExtractAll ran: Directory.EnumerateFiles(_unpackedPath, "*.js", TopDirectoryOnly).Where(IsCandidateBundleFile) yields an empty list.

Common situations: Extraction produced an empty or partial _unpackedPath (see [11]); Wand renamed/relocated its bundle filename convention; the asar header pointed at a non-standard layout; antivirus quarantined the extracted bundles.
