Stuck on an issue?

Lightrun Answers was designed to reduce the constant googling that comes with debugging 3rd party libraries. It collects links to all the places you might be looking at while hunting down a tough bug.

And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.

Calling `inflate` on data created from `Pako.deflate` returns `(null, null)`

See original GitHub issue

Some observations that I noted:

inflate fails with (null, null)


inflateSync fails with EOF:


This is probably the most important problem since one would expect either data or an error.

decompress works fine:


deflateSync : incorrect header check

It appears as though Pako has a different idea of what constitutes inflate / deflate i.e.


gzipSync: seems to correspond to pako.inflate


I noted that the builtin CompressionStream seems to correlate with what Pako does i.e. 'inflate' algorithm for Pako and CompressionStream seem to be the same.

zlib: same as gzip


zip: fails, same as deflate



I’ve no idea what’s going on here (and the issues observed may be with Pako), but I hope the above is useful feedback.
