Got this debugging another error. Filing here for reference. Original code: https://phabricator.intern.facebook.com/P59317705
const current = workInProgress.alternate;
      if (__DEV__) {
        ReactDebugCurrentFiber.setCurrentFiber(workInProgress);
      }
      const returnFiber = workInProgress.return;
      const siblingFiber = workInProgress.sibling;
      if ((workInProgress.effectTag & Incomplete) === NoEffect) {
        
        let next = completeWork(
          current,
          workInProgress,
          nextRenderExpirationTime,
        );
        stopWorkTimer(workInProgress);
        resetExpirationTime(workInProgress, nextRenderExpirationTime);
        if (__DEV__) {
          ReactDebugCurrentFiber.resetCurrentFiber();
        }
        if (next !== null) {
          stopWorkTimer(workInProgress);
          if (__DEV__ && ReactFiberInstrumentation.debugTool) {
            ReactFiberInstrumentation.debugTool.onCompleteWork(workInProgress);
          }
