blueapi controller run <plan> hangs after the conclusion of a plan

[d-perl]

with config (copied from docs...)

env:
  sources:
    - kind: dodal
      module: mx_bluesky.ui_working.devices 
    - kind: planFunctions
      module: mx_bluesky.ui_working.plans

stomp:
    host: localhost
    port: 61613
    auth:
        username: guest
        # This is for local development only, production systems should use good passwords
        password: guest

and the mx-bluesky branch i23_and_ui_testing which has some extremely simple plans of the like

@bpp.run_decorator()
def virtual_relative_move_um(x_um: float, y_um: float) -> MsgGenerator:
    """
    Used for click-to-move on an OAV. Moves the gonio a relative distance of x and y to
    bring the clicked location to the beam centre. Takes account of the goniometer omega
    position in order to do the relative move in the lab frame.
    """
    gonio = devices.vgonio()

    LOGGER.info(
        f"Current position: {yield from bps.rd(gonio.x)}, {yield from bps.rd(gonio.yh)}"
    )
    yield from bps.rel_set(gonio.x, x_um, wait=True)
    yield from bps.rel_set(gonio.yh, y_um, wait=True)
    LOGGER.info(
        f"New position: {yield from bps.rd(gonio.x)}, {yield from bps.rd(gonio.yh)}"
    )

where gonio is prepared using the old-style device_instantiation because I could set the mock arg to True there...

running

╰─>$ blueapi --config stomp.yml  controller run virtual_relative_move_um '{"x_um": 4, "y_um": 23}'

2024-11-29 12:21:44,258 - Subscribing to name='public.worker.event'

hangs forever. the plan runs successfully and the worker returns to idle state but the controller (presumably) waits for this event forever.

Hmm, not sure why it's missing the event, regardless we should probably add a timeout
