android navigation jetpack Kotlin

I'm working on a personal project and Hey everyone, I'm running into an issue that's driving me crazy... I'm working with an scenario when trying to navigate between fragments using the Jetpack Navigation Component in my Android app. Despite my setup looking correct, I keep working with the behavior `java.lang.IllegalArgumentException: No view found for id 0x7f0a0034` when I attempt to navigate from `FirstFragment` to `SecondFragment`. I've double-checked that `SecondFragment` is defined in my navigation graph and that the IDs match. Here's how I'm navigating: ```kotlin // In FirstFragment private fun navigateToSecondFragment() { findNavController().navigate(R.id.action_firstFragment_to_secondFragment) } ``` In my `nav_graph.xml`, I have defined the action like this: ```xml <action android:id="@+id/action_firstFragment_to_secondFragment" app:destination="@id/secondFragment" /> ``` The ID being referenced in the behavior message corresponds to the container view in my activity where fragments are inflated, which has this layout: ```xml <androidx.fragment.app.FragmentContainerView android:id="@+id/fragment_container" android:layout_width="match_parent" android:layout_height="match_parent" /> ``` I've ensured that I'm using the correct navigation host fragment in my activity layout: ```xml <androidx.navigation.NavHostFragment android:id="@+id/nav_host_fragment" android:name="androidx.navigation.fragment.NavHostFragment" app:navGraph="@navigation/nav_graph" android:layout_width="match_parent" android:layout_height="match_parent" /> ``` So far, I've tried cleaning and rebuilding the project, ensuring that all IDs and references are correct, and using `findNavController()` from the correct view. I've also confirmed that the fragments are properly attached when I attempt to navigate. Despite these efforts, the scenario continues. Any guidance on what might be going wrong would be greatly appreciated! This is part of a larger web app I'm building. Any ideas what could be causing this? For context: I'm using Kotlin on macOS. Any pointers in the right direction? I'm on Debian using the latest version of Kotlin. Has anyone else encountered this?
