ng-universal | Angular Universal & SEO Utilities | Server Side Rendering library

I've got an app with a universal link. When I tap the link in another app, it opens my app (except in Safari, it opens the webpage but displays a little banner at top offering to open in the app, tapping "Open" opens my app).

My issue is no code gets executed in my app.

I've put the sample code from Apple's documentation:

In my Swift iOS app I asynchronously set up the initial view controller in the AppDelegate inside didFinishLaunchingWithOptions. Now I'm adding a Universal Link such that if you go to the corresponding URL on your phone it will automatically open the right page in the app (in this case it's a password reset URL that, if correct, will open the password reset form inside the app).

I am handling the linking inside application(_:continue:restorationHandler:) (continueUserActivity) in my AppDelegate.

It works if the app is already running but otherwise the link handling happens before my app has finished setting up the initial view controller and the view controller for the deep link gets dismissed when didFinishLaunchingWithOptions returns.

How can I ensure the app is finished setting up before I present view controllers from continueUserActivity? I can't/shouldn't prevent didFinishLaunching from returning until the view controllers are set up, so the method returns before the initial view controller is presented.

I know I can check the user activity dictionary inside didFinishLaunchingWithOptions but continueUserActivity is still called (it would be much simpler if it was only called if the app was running, like how didReceiveRemoteNotification works). Is there a condition to check inside this method to defer the link handling to didFinishLaunching?

Some simplified UIApplicationDelegate code to help explain:

I am getting this error when using the latest version of angular, angularfire, and angular universal.

ng serve

No problem with regular serve...

ng add @nestjs/ng-universal

Added universal, seemed to install fine...

npm run build:ssr

Seemed to compile, some warnings, but no errors...

npm run serve:ssr

Seemed to work until I load the page on localhost with this error:

Error enabling offline persistence. Falling back to persistence disabled: Error: ENOENT: no such file or directory, open 'C:\angular projects\testProject\dist\testproject\server\src\protos\google\firestore\v1\firestore.proto'

---------Update-----------

I deleted the dist folder and rebuilt, and now I get just this error:

Error: ENOENT: no such file or directory, open 'google/protobuf/api.proto'

Here is the full error:
