The problem is that you can't call flux-in-box until the fields have been initialized, which happens inside run. This is equally true for any other low-level function where you pass the "fields" object explicitly. If you called the higher-level function (flux-in-box X (volume ...)) instead, it would print an error message about the fields not being initialized. If you add (run-until 0) before the flux line, that will initialize the fields and then it should work.
