Issue with Redux passing {type, foo} as Action parameter

[lvdang]

When using {type, foo} for the action. I am getting error below e.g. string literal BAR. Expected string literal FOO, got BAR instead HOWEVER if I use "action: Action" instead of {type, foo} is works.

type State = {}; type FooAction = { type: "FOO", foo: string }; type BarAction = { type: "BAR", foo: boolean };

type Action = FooAction | BarAction;

function reducer(state: State, {type, foo}: Action): any { switch (type) { case "FOO": return { ...state, foo }; case "BAR": return { ...state, foo }; default: return state; } }

// Errors

I'm guessing this is not the github project you meant to post this on? 🤡
