./zkCli.sh cannot create the node

in the zkCli.sh cannot create a node,and no exceptions have been thrown, but use the java client api can create that path: "/configplatform/12", I saw the same issue previously.

[zk: (CONNECTED) 2] create /configplatform/12
[zk: (CONNECTED) 3] create /configplatform/12
[zk: (CONNECTED) 4] create /configplatform/12
[zk: (CONNECTED) 5] create /configplatform/12
[zk: (CONNECTED) 6] create /configplatform/12
[zk: (CONNECTED) 7] ls /configplatform
[11, 13, 3, 4, 5, 6, 7, 8, 9, 10]
[zk: (CONNECTED) 8] delete /configplatform/12
Node does not exist: /configplatform/12
[zk: (CONNECTED) 9] get /configplatform/12
Node does not exist: /configplatform/12
