I can't quite figure out how to use the profiling build. I aliased `react-dom` to `react-dom/profiling` but I get this error:

I didn't want interactions, I just want profiling. What am I doing wrong?

To repro, use CRA, then eject, then add `react-dom` -> `react-dom/profiling` to alias in webpack prod config and build.
let firstEffect;
  if (finishedWork.effectTag > PerformedWork) {
    
    
    
    
    if (finishedWork.lastEffect !== null) {
      finishedWork.lastEffect.nextEffect = finishedWork;
      firstEffect = finishedWork.firstEffect;
    } else {
      firstEffect = finishedWork;
    }
  } else {
    
    firstEffect = finishedWork.firstEffect;
  }
  prepareForCommit(root.containerInfo);
   Invoke instances of getSnapshotBeforeUpdate before mutation.
  nextEffect = firstEffect;

      invokeGuardedCallback(null, commitBeforeMutationLifecycles, null);
      if (hasCaughtError()) {
        didError = true;
        error = clearCaughtError();
      }
