json parse is wrong for pmacct

[paolss]

example:
/home/pstaszewski/pmacct-to-elasticsearch# pmacct -l -p /tmp/epix_mem.pipe -s -O json -e | pmacct-to-elasticsearch e_mem
2022-12-20 00:18:56,105 ERROR Error loading configuration from /etc/p2es/epix_mem.conf
Traceback (most recent call last):
File "/usr/local/bin/pmacct-to-elasticsearch", line 398, in main
new_cfg = json.load(f)
File "/usr/lib/python3.8/json/init.py", line 293, in load
return loads(fp.read(),
File "/usr/lib/python3.8/json/init.py", line 357, in loads
return _default_decoder.decode(s)
File "/usr/lib/python3.8/json/decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python3.8/json/decoder.py", line 353, in raw_decode
obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting ',' delimiter: line 4 column 1 (char 69)

Or for json
/usr/local/bin/pmacct-to-elasticsearch e_print
