add_meeting_registrant results in RegistrantConfirmation error

[gpe5280]

From the command line:

$ python

Type "help", "copyright", "credits" or "license" for more information.
>>> from pyzoom import ZoomClient
>>> client = ZoomClient(ZM_KEY, ZM_SECRET)
>>> client.meetings.add_meeting_registrant(XXXXXXX, first_name='John', last_name='Public', email='[email protected]', job_title='Boss')

The following error occurs, however, the registrant is added to the meeting roster.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/websites/domains/stoicagilist.com/system/lib/python3.10/site-packages/pyzoom/_client.py", line 121, in add_meeting_registrant

pydantic.error_wrappers.ValidationError: 1 validation error for RegistrantConfirmation
join_url
  field required (type=value_error.missing)

I tried adding the join url to the parameter list (join_url='https://us02web.zoom.us/j/XXXX?pwd=XXXX'), since it is different from the registration url, but the result was the same.

(PS. Thank you for this excellent library. It has saved me hours of coding!)

Edited to add information...

As I worked to add more functionality to my project, specifically add_and_confirm_registrant, this error became more problematic. The "fix" for me so far has been to change the following code in schemas.py:

class RegistrantConfirmation(MyZoomBase):
    registrant_id: str
    id: int
    topic: str
    start_time: str
    join_url: str

To:

class RegistrantConfirmation(MyZoomBase):
    registrant_id: str
    id: int
    topic: str
    start_time: str
    join_url: Optional[str]

Without this change I was able to add a registrant, but could not approve them programmatically.
