Bug Report

Capacitor Version

PASTE OUTPUT HERE

Platform(s)

iOS

Current Behavior

firebase v9 refuses to connect on iOS due to the following errors below. On safari, android, chrome, everything else, works fine.

[Error] Cross-origin redirection to http://developers.google.com/ denied by Cross-Origin Resource Sharing policy: Origin capacitor://localhost is not allowed by Access-Control-Allow-Origin. [Error] XMLHttpRequest cannot load https://apis.google.com/_/jserror?script=https%3A%2F%2Fapis.google.com%2F_%2Fscs%2Fabc-static%2F_%2Fjs%2Fk%3Dgapi.lb.pt_BR.JNlq9XF7n9c.O%2Fm%3Dgapi_iframes%2Frt%3Dj%2Fsv%3D1%2Fd%3D1%2Fed%3D1%2Frs%3DAHpOoo_CgjdRKayLAI-SffAgrENAd8_UBA%2Fcb%3Dgapi.loaded_0%3Fle%3Dscs&error=x`capacitor&line=183 due to access control checks. [Error] Failed to load resource: Cross-origin redirection to http://developers.google.com/ denied by Cross-Origin Resource Sharing policy: Origin capacitor://localhost is not allowed by Access-Control-Allow-Origin. (jserror, line 0)

Expected Behavior

Shoulda connect normally. Appears that the domain from http://developers.google.com/ appears to be refusing the connection, tho version 8 of firebase worked normally.

Code Reproduction

Just imported all the libraries from firebase

Other Technical Details

npm --version output: 8.5.5

node --version output: 12.22.8

pod --version output (iOS issues only): 1.10.2

Hi ! I got the same problem, it was was caused by a bad initialisation of FireAuth in my case.

See how to properly initialise FireAuth here : https://stackoverflow.com/questions/71630326/firebase-authentication-sticks-capacitor-ionic-on-ios

Did you figure out anything on this error, @JSilva6? I’m having the same issue.

For now I went back to v8.
