Zlib Deflate Parse Failed!
Error message
Zlib Deflate Parse Failed!
What it means
Placeholder string shown in the deflate viewer when decompression fails. formatStr calls $util.zippedToString(content, 'deflate') → zlib.inflateSync, which expects a zlib-wrapped deflate stream (78 xx header + Adler-32 trailer). Any throw or empty output makes formatStr false, and newContent displays 'Zlib Deflate Parse Failed!' meaning the bytes are not a valid zlib-wrapped deflate stream.

Solutions
- Check the first bytes: zlib-wrapped deflate starts with 78 01/9c/da; otherwise switch to the DeflateRaw viewer
- Verify the stream is complete (Adler-32 trailer present) in the hex view
- Strip any outer encoding (hex/base64) before expecting deflate bytes
- Fix the producer to emit zlib.deflateSync output if you standardize on this viewer
Example fix
// before
return 'Zlib Deflate Parse Failed!';
// after - propagate the zlib reason
try {
return zlib.inflateSync(buf).toString();
} catch (e) {
return `Zlib Deflate Parse Failed: ${e.message}`;
} Defensive patterns
Strategy: type-guard
Validate before calling
const ok = typeof this.$util.zippedToString(buf, 'deflate') === 'string';
if (!ok) { /* fall back to deflateRaw / hex viewer */ } Type guard
const isZlibDeflate = (buf) => typeof $util.zippedToString(buf, 'deflate') === 'string';
Prevention
- Standardize writers on zlib-wrapped deflate (zlib.deflateSync) when using this viewer
- Check the 78 xx zlib header in hex view before assuming the mode
- Use the app's isDeflate detection to pick the viewer automatically
When it happens
Trigger: Viewing a key labeled deflate whose bytes are actually raw deflate (no zlib wrapper) — inflateSync throws 'incorrect header check'; truncated stream → 'unexpected end of file'; stream produced by a non-zlib container (e.g. HTTP chunk framing still attached); empty decompressed output also maps to false.
Common situations: Writers using raw deflate (Z_SYNC_FLUSH websocket frames, 'deflate-raw') versus zlib-wrapped deflate confusion; content that is deflate-compressed then hex/base64 encoded with the outer layer not stripped; corrupted values from partial writes.
