Unknown code: -1237188481

I've got this weird exception:

2017-12-24T14:15:37.021Z - error: uncaughtException Error: Unknown code: -1237188481
    at validateCode (project-folder/node_modules/node-zookeeper-client/lib/Exception.js:51:15)
    at Function.create (project-folder/node_modules/node-zookeeper-client/lib/Exception.js:140:5)
    at ConnectionManager.Object.<anonymous>.ConnectionManager.onSocketData (project-folder/node_modules/node-zookeeper-client/lib/ConnectionManager.js:570:35)

Not sure if it's related to this package since I'm using kafka-node.
I'm also not sure what causes it; I'm just sending a message and listen to the message (straightforward use case).

I'm seeing similar exception as well, with different code -321257332, running Node.js v6.11.5 on Linux

/app/node_modules/node-zookeeper-client/lib/Exception.js:51
        throw new Error('Unknown code: ' + code);
        ^

What version of the zookeeper are you using? What operations were you doing when the exception happened?

[fbo3264]

@alexguan I was able to solve the issue. Unintentionally I was opening several zookeeper-connections almost at the same time, i.e. while the connect()-call was still in progress. It works fine now :)

[grayguo]

@alexguan I'm using node-zookeeper-client@0.2.2 and the code simply does connect() to the Zookeeper server.

Some useful infomation:
step1. Create ZkClient and connect as normal
step2. Disable your network and wait for about 1 min(due to zk heap)
step3. Enable the network will throw this Error

@Catlite91 which version of zookeeper are you using?

[Catlite91]

@alexguan 3.4.8
