I updated my node and npm versions and then i started getting the following Error:

Uncaught TypeError: this._callbacks[id] is not a function

It sounds like you are registering something with the dispatcher that isn't a function.

This happened to me because I was setting an internal variable in the Flux store as

this._var = true

instead of

_var = true

Simple mistake and took me a fair bit of debugging to catch that. Hope it helps anyone else with this issue.

i had to remove dispatcher.register(this.handleActions); cause i deleted handleActions()
