Sorry I'm beginner with ionic ,
Tell me if i'm wrong but when i tried to do the "Getting Started", it's raised me an error :
Type 'string | undefined' is not assignable to type 'string'.
[ng] Type 'undefined' is not assignable to type 'string'.

I found this fix.

A member of the Team first needs to authorize it.

Thank you for the PR! Looking into this further, it looks like the better approach is to mark webviewPath as optional in the UserPhoto interface, so you avoid the error without having to assert a variable that may not actually be defined. The React and Vue versions of the guide take this approach.

I've created a separate PR that makes this change instead: #2926 You'll be given co-author credit when the PR is merged. Closing this one out in favor of the newer one.
