Invalid Channel BadConnectionClosed error on read

[Mradvanyi123]

I'm receiving "Invalid Channel BadConnectionClosed" when reading from an OpcUa server running in the same Node-RED instance.
I'm assuming the error is thrown here:
https://github.com/mikakaraila/node-red-contrib-opcua/blob/master/opcua/102-opcuaclient.js#L1208

Why is this error not thrown in the form node.error('message',msg) ?
Why are some errors thrown node.error('message') and others node.error('message'.msg) ?
In the case of a failed read action, what is the reason for not retrying?
