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.
