AttributeError: 'NoneType' object has no attribute 'questions' #465

I am getting an exception when running vn.ask on a linux server.

~ $ python
>>> import vanna
>>> from vanna.remote import VannaDefault
>>> vn = VannaDefault(model='chinook', api_key=vanna.get_api_key('[email protected]'))
>>> vn.connect_to_sqlite('https://vanna.ai/Chinook.sqlite')
>>> vn.ask('What are the top 10 artists by sales?')
'NoneType' object has no attribute 'questions'
(None, None, None)
>>> 

Is there a reason this code here returns a None value, inevitably causing this NoneType error ?
What does it mean and how to prevent this from happening ?

(

vanna/src/vanna/vannadb/vannadb_vector.py

Line 190 in a72b842

return None

)

When checking why the mentioned code was returning none, I was able to get this error out:

vn_rpc_call(method="get_related_training_data", params=params)
Traceback (most recent call last):
File "", line 1, in
NameError: name 'vn_rpc_call' is not defined
vn._rpc_call(method="get_related_training_data", params=params)
{'error': {'code': -32600, 'message': 'Invalid Request: No email'}, 'jsonrpc': '2.0'}
A better exception + error message would be useful instead of returning None.
What email though ?
