not able to build IOS due to AppAuth error

[raykleijngeld]

Hi,

I have the following reference in my pubspec.yaml

firebase_core: ^1.1.0
cloud_firestore: ^2.0.0
firebase_messaging: ^9.1.3

Android version builds fine no issues.

iOS build running pod install gives the following error:

Analyzing dependencies

firebase_core: Using Firebase SDK version '7.11.0' defined in 'firebase_core'

fatal: Remote branch 1.4.0 not found in upstream origin

Does anyone know how to fix this?

Thanks
