Save dictionary of size 17408 into file out/dict

for FILE in `ls out/*.js`; do zstd  --force -D out/dict -o ${FILE}.zst ${FILE}; done
out/0001.js          : 13.57%   (  1.58 KiB =>    219 B, out/0001.js.zst)
out/0002.js          :  9.71%   (  1.59 KiB =>    158 B, out/0002.js.zst)
out/0003.js          : 10.85%   (  1.58 KiB =>    175 B, out/0003.js.zst)
out/0004.js          :  9.65%   (  1.54 KiB =>    152 B, out/0004.js.zst)
...

Now when I do:

pako.inflateRaw(file0001, { dictionary: dict });

I get:

Uncaught invalid stored block lengths
inflate @ pako_inflate.js:3185
inflateRaw @ pako_inflate.js:3202
(anonymous) @ VM3891:1

What am I doing wrong? I confirmed zstd can use the dictionary to inflate again.

I am pretty desperate to make this work and very short on time. I am willing put a 200 dollar bounty on an answer within this evening.
