Error Writing Cache SW.JS

Hello there !

I tried to make game on Android, then make iFrame to open my HTML game.

But my game cache is error when caching the game. ( i already make 3 game, 2 game with no error cache, and 1 error cache)

I just have this error from the console log on logcat.

Can someone help ?

Caching work if i play it on web, but when i play it on android with iFrame, its not cache the game, and show error like that

I tried to edit SW JS to get object DOMException, then message from error SW js like this
