According to the documentation on Deep Links in Compose, when matching a URI deep link, placeholder values should be placed in back stack entry's arguments Bundle with the same name as the placeholder. For example, consider the following link is deep-linked:

https://example.com/MyApp/Code=123456

Previously, you could match this URI with something like the following:

composable<MyComposable>(
            deepLinks = listOf(
                navDeepLink {
                    uriPattern = "example.com/MyApp/Code={code}"
                    action = Intent.ACTION_VIEW
                }
            )
        ) { backStackEntry ->
            // Notice how you could obtain the code from arguments by the same name as the placeholder value
            val myCode = backStackEntry.arguments?.getString("code")

            MyComposable(
                code = myCode
            )
        }

This is no longer the case as the documentation suggests. In order to obtain the URI from the deep link, you now have to use:

val code: Intent = backStackEntry.arguments?.get("android-support-nav:controller:deepLinkIntent") as Intent
val uri = code.data
...

The entire deep link Intent is getting put into the arguments Bundle, where it should only be a string of the placeholder value from the URI. Second, no matter what I attempted to name my placeholder value in the URI, the name in the Bundle stayed a constant "android-support-nav:controller:deepLinkIntent" as well as staying in the Bundle as an Intent rather than just the string.
