Service Worker Uncaught (in promise) DOMException

My Service Worker Troubles with error, Uncaught (in promise) DOMException. My SW runs perfectly, and gives a prompt to install PWA when on mobile, but it gives this error. My url is Milyin. It will take 2-3 visits for this error to start coming in Console log.

Just 3 visits caused it to produce over 260 errors for it. I am not able to debug it. I assume that this is because the SW has consumed all storage space in my device. Because if i reload the page using F5, it shows error, but a refresh with CTRL + SHIFT + R, makes no error.

//This is the service worker with the Advanced caching

const CACHE = "Milyin";
