Research direction

Start by tracing fireStateAtPath through the Android path and inspect the stack-trace locations in Artboard.kt and RiveFileController.kt, especially getOrCreateStateMachines and processAllInputs. Confirm the Android implementation handles the state-machine path without looking up an empty name; done means fireStateAtPath no longer crashes while fireState continues to work.

Description

Description

The app (expo client) crashes when trying to use fireStateAtPath

Provide a Repro

The issue seems to be that it doesn't find the StateMachine in the native side.
Sadly I cannot provide a riv file but it works on both iOS and web - with fireStateAtPath - so the riv file is fine.

fireState also works fine

        const fireStateOrfireStateAtPath = (stateName: string) => {
          if (stateName.includes("/")) {
            const [state, ...path] = stateName.split("/").reverse();
            riveRef.current?.fireStateAtPath(state, path.reverse().join("/"));
          } else {
            riveRef.current?.fireState(stateMachineName, stateName);
          }
        };

Any ideas? Thank you ❤️
