Eventbridge put_events doesn't seem to support custom event buses

See below - message received fine for the default event bus (unspecified), but not received if one specifies a custom event bus

$ python test_moto_event_bus.py
custom bus [False] -> message received [True]
custom bus [True] -> message received [False]

DetailType: my-detail-type
""")

Statement=yaml.safe_load("""

Principal:
  Service: events.amazonaws.com

Resource: "*"
""")

            count > nmax):

@bblommers you’re 100% right - sorry for the trouble but many thanks. Closed.

Hey @jhw - Moto hasn’t specifically signed up for any, and I haven’t personally used any bounty programs either.

With those caveats out of the way: Is it possible to use a generic program, like Bountysource.com? The Github-authentication seems broken at the moment, so I can’t login and verify, but as far as I know that’s a pretty generic (project independent) way of posting and resolving open source bounties.
