Ingestion Problems

Hey, I followed the steps from the documentation to configure my own Echoprint server, and everything seems to work fine. But when I`m trying to ingest the data files I reveive this:

raluca@ubuntu:~/Desktop/echoprint/util$ python fastingest.py -b /home/raluca/Downloads/dump/dump/echoprint-dump*.json 1/5 /home/raluca/Downloads/dump/dump/echoprint-dump-1-1-1.json Traceback (most recent call last): File "fastingest.py", line 63, in fp.ingest(codes, do_commit=False) File "../API/fp.py", line 586, in ingest get_tyrant().multi_set(codes) File "../API/pytyrant.py", line 307, in multi_set self.t.misc("putlist", opts, lst) File "../API/pytyrant.py", line 540, in misc return list(self._misc(func, opts, args)) File "../API/pytyrant.py", line 524, in misc socksuccess(self.sock) File "../API/pytyrant.py", line 172, in socksuccess raise TyrantError(failcode) pytyrant.TyrantError: 1

Do you have any idea why ?
