Error: length of property name should not be greater than 256 [CentOS 7 x64 & Win 10 x64]

On both linux and windows 64-bit systems I received the following message when trying:

WIN10 x64:

const binding = require('node-shared-cache')
undefined
obj = new binding.Cache("test", 512 * 1024);

CentOS 7 x64:

const binding = require('node-shared-cache')
obj = new binding.Cache("test", 512 * 1024);
Error: length of property name should not be greater than 256

Please let me know if it is a bug or I am doing something wrong?

However if I just igoner errors and try to set 'obj' property to some value it succeeds:

> obj.foo = 1
1
> obj.foo
1

But obj.set property is undefined:

> obj.set
undefined
> binding.set
undefined

NodeJS version: v 8.9.3

It's mentioned in the docs:

"key length should also not be greater than 256"
