Hello,

some cluster items returns no value. One example:

#./proxysql.py get cluster mysql_query_rules
Traceback (most recent call last):
File "/opt/bin/proxysql.py", line 137, in
args.func(args)
File "/opt/bin/proxysql.py", line 68, in get_proxysql_cluster
WHERE hostname in( "%s") and name in ("%s");""" % (socket.getfqdn(),args.param))[0]['checksum']
IndexError: list index out of range
