Unable to pass attributes to purchase_ship()

[ipaulo]

Using the new pydantic style for json_body, I can't seem to pass attributes to purchase_ship().

from spacetraders import AuthenticatedClient

API_BASE_URL="https://api.spacetraders.io/v2"

mytoken = "SECRET"

client = AuthenticatedClient(
    base_url=API_BASE_URL,
    token=mytoken,
)

shipyard = "X1-DF55-69207D"
resp = client.fleet.purchase_ship(shipType="SHIP_PROBE", waypointSymbol=shipyard)
print(resp.content.decode())

resp = client.fleet.purchase_ship(ship_type="SHIP_PROBE", waypoint_symbol=shipyard)
print(resp.content.decode())

The API response from the first request (with shipType=) is:

{"error":{"message":"Request could not be processed due to an invalid payload.","code":422,"data":{"shipType":["The shipType field is required."],"waypointSymbol":["The waypointSymbol field is required."]}}}

The second request (with shib_type=) gives this python error:

Traceback (most recent call last):
