IllegalStateException in production

[arlee17]

Hello,

my app has been in production for a few months now.
Everything works correctly, but we have noticed a very frequent error:
Navigator.kt line 46 in dev.hotwire.navigation.navigator.Navigator.getCurrentDestination

Google Play Console log:

New Relic flow:

Is anyone else having this issue? we are using the latest version (1.2.4) .

Is there a fix?

Thanks

Are you using tabs or a single navigator host instance?

Hi Joe, I'm using tabs.

My tabs are built in the “traditional” way, without following Hotwire's examples, as I haven't updated to follow your way.
Example:

private fun makeNavigation() {
    bottomNav = requireActivity().findViewById(R.id.navigation_bottom)
    bottomNav.isItemHorizontalTranslationEnabled = true
    bottomNav.setOnItemSelectedListener {

      if (!isAdded) {
        return@setOnItemSelectedListener false
      }

      when (it.itemId) {
        R.id.HomeFragmentItem -> {
          navigateTo(getBaseUrl())
          true
        }

        R.id.CatalogFragmentItem -> {
          navigateTo(getCatalogUrl())
          true
        }

        R.id.AccountFragmentItem -> {
          navigateTo(getAccountUrl())
          true
        }

        R.id.CartFragmentItem -> {
          navigateTo(getCartUrl())
          true
        }

        else -> {
          false
        }
      }
    }
  }
