echoprint-inverted-index gives error with piping large dump file to it

[abb4s]

actually i wanted to test echoprint by its database : http://echoprint-data.s3.amazonaws.com/echoprint-dump-1.json
and i try to do this :
cat echoprint-dump-1.json|jq -r '.[].code' | echoprint-inverted-index index.bin
and it gives this error :
Traceback (most recent call last): File "/usr/local/bin/echoprint-inverted-index", line 19, in <module> create_inverted_index(streamer(sys.stdin), args.indexfile) File "/usr/local/lib/python2.7/dist-packages/echoprint_server/lib.py", line 57, in create_inverted_index for batch_index, batch in enumerate(split_seq(songs, 65535)): File "/usr/local/lib/python2.7/dist-packages/echoprint_server/lib.py", line 30, in split_seq item = list(itertools.islice(it, size)) File "/usr/local/lib/python2.7/dist-packages/echoprint_server/lib.py", line 78, in parsing_code_streamer yield decode_echoprint(line.strip())[1] File "/usr/local/lib/python2.7/dist-packages/echoprint_server/lib.py", line 42, in decode_echoprint unzipped = zlib.decompress(zipped) zlib.error: Error -5 while decompressing data: incomplete or truncated stream

i think it happens just when file is being larger , i tested it with small json files and it works.
any one encounter with this error ?
is this a bug or the problem is just mine ?

This is likely happening because there is a null or a "" in the "code" field of one of the objects.

Hi,
stumbled into this as well. Just put one egrep to avoid the nulls. This is what I did:

$ cat fingerprint.json | jq -r '.[].code' | egrep -v null$ | echoprint-inverted-index index.bin
