Hi need help with an error i got with Zustand/React/Vite -> useEffect must not return anything besides a function

[eitai]

Hey guys, I got an error
useEffect must not return anything besides a function, which is used for clean-up. You returned: [object Object] at App .
when I try to set Data into a state in Zustand that's the error I get. any ideas?

@eitai would you mind sharing us the whole component with the useEffect statement included?

[eitai]

Hi Dbritto, that's the thing, it's not the component it is complaining about the useEffect behind the scene of the Zustand.

@eitai in that case the error is not related to zustand but the code itself. As far I see in the compiled version you are returning an object in your useEffect statement which is wrong.

Note: you can only return functions or undefined in useEffect statements

Yeah u right just got it solved , apparently in App I can return things in useEffect , thanks anyway :)
