I ran into this myself when I first tried using beangrow. Debugging into
the code a bit, I believe the problem is that beangrow doesn't support
investments with the "core" currency (i.e. USD). If you look at the example
ledger file and config in the beangrow repo, you'll see that all of the
configured investments are for a non-USD commodity.
