Airtable to Power BI using Personal Access Token "cannot convert the value null to type Record

[Rhode_Ninja]

Hello Community,

First post here. I am attempting to connect my Airtable to Power BI.

I am receiving the following error message in Power BI

• Expression.Error: We cannot convert the value null to type Record.
  Details:
  Value=
  Type=[Type]

I am following this guidance and using a Personal Access Token. I setup Power BI Parameters successfully but received the error code in the Query. I suspected that it may be the M Code so I followed a link to a GitHub resource for alternate code.

• "If the above script seems to be causing an error, then please refer to this GitHub resource, as the code may have changed.

I have tried both versions of the M code.
I don't know enough about tracking down this error code. Any ideas of what it might be?
All assistance is greatly appreciated.

For Authentication, it is recommended to use "Anonymous" which doesn't work for me no matter what

My Date Source Settings on current file as well as Global are all set to Anonymous
