Authorization Error: unsupported URL

[brycnguyen]

I am having issues with using a custom redirect URL on iOS where I am unable to get back a response from my request when logging in. For example my redirect uri is: com.some.random.app:/callback

It seems to be related to the issues above.

Thank you @brycnguyen for this code, it solved my problem as well. After upgrading to Expo 52 and iOS target 15.1, something broke with the custom schema redirect. I could see successful responses in the network panel but would get this -1000 Authentication error.

Hi,
not 100% sure if this is the same issue, but we had issues with the redirect and expo aswell.

okta-oidc-ios/Sources/OktaOidc/Common/OktaOidcConfig.swift

Line 121 in ff0b914

delegate: RedirectBlockingURLSessionDelegate.shared,

the custom delegation does not work well with expo dev tools which injects a custom protocol handler
https://github.com/expo/expo/blob/32ceab8e8f23a5b7439e55a223330c66fd308de0/packages/expo-dev-launcher/ios/DevLauncherNetworkInterceptor.swift#L75

We are currently forced to patch ExpoRequestInterceptorProtocol.swift to not interfere if our custom scheme is used.

Hi @cbartel,
how exactly do you patch ExpoRequestInterceptorProtocol, can you share ? I have the same problem and I think patch expo-dev-launcher will be easier than patch the pod and okta-oidc-ios.
Thanks
