Error: corrupted input

I have transferred xz file into JS using XMLHttpRequest. The content type of response is application/x-xz, and I checked response content which seems complete. Then I use LZMA.decomporess(request.response, ...) and got corrupted input error. What is wrong in my case? Thanks in advance.

@xseman For my needs, I switched to https://github.com/cscott/lzma-purejs. It generates proper raw lzma. Only it adds some padding (additional information) to the end of file, but I just trimmed that and can extract with comnand line xz.

Also forked lzma-purejs, but basically I made it es6 module and reorganised some components, so it can be tree shaken.| https://github.com/mauron85/lzma-purejs

Same problem. Testing with xz raw:

# compress into raw format
echo "hello" | xz -c --lzma1=lc=3,lp=0,pb=2 --format=raw > qr.xz

# test decode with xz - prints hello
cat qr.xz | xz -d --lzma1=lc=3,lp=0,pb=2 --format=raw

Try to decode with LZMA-JS

const fs = require("fs");
const LZMA = require("lzma");

const path = 'qr.xz';
const file = fs.readFileSync(path);
const byteArray = new Uint8Array(file);
const decomp = LZMA.decompress(byteArray);
console.log(decomp);

Fails with exception:

            throw new Error("corrupted input");

Same problem occurs, when I try to decompress file created with LZMA-JS with xz:

cat qr.xz | xz -d --lzma1=lc=3,lp=0,pb=2 --format=raw
