Zlib Gzip Parse Failed!

Error message

Zlib Gzip Parse Failed!

What it means

Placeholder string shown in the gzip viewer's decoded-content pane when decompression fails. formatStr calls $util.zippedToString(content, 'gzip') (src/util.js:164), which runs zlib.gunzipSync and returns the decoded UTF-8 string — or false on any throw or empty result. newContent falls back to 'Zlib Gzip Parse Failed!' whenever formatStr is not a string, so the message means: the stored bytes are not a valid gzip stream.

Solutions

1. Check the value is really gzip: first bytes should be 1f 8b (hex view)
2. If it is raw deflate, deflateRaw, or brotli, switch the viewer mode accordingly
3. Inspect in the binary/hex viewer for truncation or an encryption layer
4. If you control the writer, verify it flushes complete gzip streams (e.g. gzipSync vs streaming Gzip without .end())

Example fix

// before
return 'Zlib Gzip Parse Failed!';

// after - surface the zlib reason
// in util.js, return the error for display
try {
  return zlib.gunzipSync(buf).toString();
} catch (e) {
  return `Zlib Gzip Parse Failed: ${e.message}`;
}

const ok = typeof this.$util.zippedToString(buf, 'gzip') === 'string';
if (!ok) { /* do not render gzip viewer; fall back to hex */ }

// same predicate the app itself uses (src/util.js isGzip)
const isGzip = (buf) => typeof $util.zippedToString(buf, 'gzip') === 'string';

When it happens

Trigger: Viewing a key whose type is detected/labeled gzip but whose bytes lack the gzip magic (1f 8b) or are truncated; double-gzip data; zlib.gunzipSync throwing 'incorrect header check' or 'unexpected end of file'; decompressed length 0 also maps to false.

Common situations: Values compressed with raw deflate instead of gzip; payload encrypted before compression; partial writes/corruption; content type misdetected because a previous key in the session was gzip.
