BlueapiClient reports successful response on device move when actually fails

[oliwenmandiamond]

When trying to use BlueapiClient, I tried to move a shutter as shown below for i09:

>>> from blueapi.client import BlueapiClient
>>> bc = BlueapiClient.from_config_file("/home/xol73553/Documents/BLUESKY/i09_blueapi_client_config.yaml")
>>> for device in bc.devices:
...     print(device)
... 
<Response [200]>
dcm
lakeshore
psi2
psj2
psi1
psk1
fsj1
psj1
jphase
pgm
jgap
iid
ienergy_order
fsi1
...
>>> devices = bc.devices
>>> plans = bc.plans
<Response [200]>
>>> plans.move({devices.fsj1: "OUT"})
<Response [201]>
<Response [200]>
>>> plans.move({devices.fsj1: "IN"})
<Response [201]>
<Response [200]>

(I modified the code to print the response it received). As you can see, it is reporting the status as success, however the shutters were never moved... Looking at the logs in BlueAPI, I can see the following:

The above exception was the direct cause of the following exception:

The shutter never moved because the plan failed because it didn't use a valid enum. This needs to be changed in BlueAPI so that this error is propagated to the user and doesn't falsely return a valid response.
