I think I explained it clearly the first time. GoogleChrome/workbox#1790 It’s kind of out of our reach. Just ignore it as it will not break anything. @jmunckhof

Oh Okay, Is there a way to suppress these warnings?

Hi,

Like it is described in https://github.com/GoogleChrome/workbox/issues/1790 there is no good way to fix this (especially from Quasar side). However, we do not want to supply a dummy service worker in dev mode because that would make the whole developer experience awful. You’d be able to test your service worker only on production builds which adds a lot of overhead and time lost. But like we wrote in our docs, when you develop an app and your goal at that moment does not include handling the service worker, you can temporarily switch to “quasar dev -m spa”. Wish the workbox team would find a way to avoid the issue, but at the moment, it is what it is.
