Set TempData in ViewComponent

Question

I want to set TempData in View Component so that i can check it in Login Action when there is error in View Component.

Here is my .ts file code

window.onload = function () {

    fetch('../Controller/ActionName',
        {
            headers: {
                RequestVerificationToken: (<HTMLInputElement>document.getElementById("Token")).value
            }
        })
        .then((response) => {
            if (response.status != 200) {
                redirectToHomePage();
            }
            response.text().then((data) => {
                document.getElementById("Id")!.innerHTML = data;
            });
        });

    // Redirect to home page
    function redirectToHomePage() {
        var url = window.location.origin;
        window.location.href = url + '/Login/Login/';
    }
};

Below is the ViewComponent code

public IViewComponentResult TestViewComponent()
{
    try
    {
        // Do code here
    }
    Catch(Exception ex){                
         TempData["Error"] = "Err msg";
         return View(viewName)
    }

    return View(viewName);
}

TempData is set correctly in ViewComponent, but when response get back from .ts file from redirectToHomePage() function to Login/Login TempData will be null.

So how to get TempData in Login action

Thank you in advance

Here is a definition of ViewComponent.TempData,And in the link you can see the TempData only have get method,So you cannot pass the TempData to Login/Login.
