Uncaught Reference Error: data is not defined at sw.js:370

Hi, for a few months I have been getting this error whenever I use my Firebase plugins.

This happens whenever I use Firebase Authentication.

Uncaught Reference Error: data is not defined at sw.js:370

What might be the issue? It seems it is trying to warn about something. Thanks

Ah okay. It is the Firebase Authentication service that posts to service workers. It doesn't affect the experience however (except a bit higher latency and refreshing cookies and stuff).

Also a reason why Firebase does this is that:

service workers are restricted to run from the same origin, there is no risk of CSRF since a website of different origin attempting to call your endpoints will fail to invoke the service worker

-from firebase.google.com/docs/auth/web/service-worker-sessions

Maybe a bit of support for network in swjs would be great in future?

Thanks.
