Zlib DeflateRaw Parse Failed!

Error message

Zlib DeflateRaw Parse Failed!

What it means

Placeholder string shown in the raw-deflate viewer when decompression fails. formatStr calls $util.zippedToString(content, 'deflateRaw') → zlib.inflateRawSync, which expects a bare DEFLATE stream with no zlib header or checksum. Any throw or empty output makes formatStr false and newContent renders 'Zlib DeflateRaw Parse Failed!', meaning the bytes are not a valid raw deflate stream.

Solutions

1. Hex-check the payload: raw deflate has no 78 xx header — if present, switch to the Deflate viewer
2. Confirm the writer used raw mode (zlib.deflateRawSync / flate -raw / Z_RAW)
3. Check for truncation or double encoding before the deflate layer
4. Standardize producer and viewer on one deflate variant

Example fix

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

// after - propagate the zlib reason
try {
  return zlib.inflateRawSync(buf).toString();
} catch (e) {
  return `Zlib DeflateRaw Parse Failed: ${e.message}`;
}

const ok = typeof this.$util.zippedToString(buf, 'deflateRaw') === 'string';
if (!ok) { /* fall back to zlib-wrapped deflate viewer / hex */ }

const isRawDeflate = (buf) => typeof $util.zippedToString(buf, 'deflateRaw') === 'string';

When it happens

Trigger: Viewing a key labeled deflateRaw that actually carries a zlib wrapper (78 xx header) — inflateRawSync fails on the bogus first byte; truncated stream; data produced by gzip with the header stripped incorrectly; empty output mapping to false.

Common situations: WebSocket permessage-deflate fragments (raw deflate) confused with zlib-wrapped deflate; Redis values written from Node zlib.deflateRawSync vs zlib.deflateSync mixed up between services; corruption from partial writes.
