TypeScript error when setting a component's state: Argument of type 'X' is not assignable to parameter of type '() => void'

I am having a TypeScript error when calling setState:

That's what I am actually doing:

  updateRequests(requests: any, cb:Function|null = null) {    this.setState(      {        requests: {          ...this.state.requests,          items: requests,          loading: false,        },      },      () => {        if (cb) cb();      }    );

Here's a Component state:

export interface IServersScreenState {  requests: {    items: [];    loading: boolean;    statuses: {};    page: number;    lastPage: number;    scrollLoading: boolean;  };}

Don't actually understand why it's happening like that, because I don't have any declaration in the state, that requests needs to be look like ()=>void

here's my setState:

  setState<T>(...args: T[]) {    if (this.__mounted__) {      //@ts-expect-error spread error      super.setState(...args) as $TSFixMe;    }  }
