'ERR_HTTP2_PROTOCOL_ERROR when using TempData in ASP.NET Core 6
When I don't use TempData, the page works fine, but when I use it I get the following error.
This site can’t be reachedThe webpage at https://localhost:44332/Home/UploadFile might be temporarily down or it may have moved permanently to a new web address.
ERR_HTTP2_PROTOCOL_ERROR
Here's the code of the controller
TempData["Response"] = responseString;
return RedirectToAction("Index");
Any ideas??
