Error type of params in callback of StatefulPromise<T>.progress()

[CubeSugarCheese]

note that there two diffrent overloads of progress method.

    /**
     * Add an event listener which triggers when data receiving from server.
     */
    progress(callback: (received: string, total: string) => void): StatefulPromise<FetchBlobResponse>;

    /**
     * Add an event listener with custom configuration
     */
    progress(config: { count?: number; interval?: number }, callback: (received: number, total: number) => void): StatefulPromise<FetchBlobResponse>;

In fact, no matter which overload is called, the type of received and total are always string, not number.
It can prove by typeof.

Thank you. Yes would have to cast the types. I will take a look if I can not just adapt that.
There are the same issues e.g. with lstat
