Authorize never returns after async call

Issue

I have been trying to implement a solution where the “Reset Password” option is handled when a user is attempting to authorize with my app. I came up with the below, but when this executes the authorize call never returns. It doesn’t return with a success or error. I have also noticed this will randomly happen during development when I’m reloading the app several times. It will enter my auth function and never return, thus hanging until I clear cache, clear data and restart the app.

export const auth = () => {
    return async(dispatch) => {
        var resetEndpoint = "https://login.microsoftonline.com/giftwizit.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1_secretreset1"
        dispatch(authStart())
        try {
            console.log("in auth function");
            const authState = await authorize(authCfg.config);
            // Store token info in asyncStorage
            dispatch(authStoreToken(authState));
        }catch(error) {
            // dispatch(authFail(error));
            if(error.message.indexOf("AADB2C90118") !== -1){
               await authorize({
                   ...authCfg.config,
                   serviceConfiguration:{
                       ...authCfg.config.serviceConfiguration,
                       authorizationEndpoint: resetEndpoint
                   }
               }).then((result) => {
                   console.log(result);
               }).catch((e) => {
                   console.log(e);
               });
               console.log("Password reset complete");
            }else {
                console.log(error);
            }
        }
    }
}

Environment

• Your Identity Provider: e.g. IdentityServer 4 / Okta / Azure Azure

• Platform that you’re experiencing the issue on: iOS / Android / both Android

• Are you using Expo? No

Same here

UPD (2hrs ago + 1 iOS Developer): I have fixed my case:

1. Azure AD will give you a returnUrl like msauth.[BUNDLE_ID]://auth
2. It’s IMPORTANT to ADD SLASH AT THE END in your config: msauth.[BUNDLE_ID]://auth/
3. Then it will works.

The problem code is here — https://github.com/openid/AppAuth-iOS/blob/master/Source/OIDAuthorizationService.m#L125 This method on line — https://github.com/openid/AppAuth-iOS/blob/master/Source/OIDAuthorizationService.m#L111 returns false.

You’re welcome.

Even though this issue is aimed at Android, we noticed that the iOS solution provided by @isnifer is fixing both our iOS and Android-issues for us.

Normal Microsoft accounts use a redirect URI without a trailing slash Azure AD accounts use a redirect URI including a trailing slash

Both, however, work with the trailing slash. We have updated our configuration to add the trailing slash and now both Android and iOS workperfectly.

Thanks @isnifer.
