Airtable client's get method does not work for me

[andrasnagy-data]

Code:
at_client = airtable.Airtable("Beta testing", AIRTABLE_TOKEN)
at_client.get("People")

Error:
Traceback (most recent call last): File "/Users/andrasnagy/Desktop/sensae/code_base/projects/slack-app/main.py", line 22, in <module> at_client.get("People") File "/Users/andrasnagy/Desktop/sensae/code_base/projects/slack-app/.venv/lib/python3.11/site-packages/airtable/airtable.py", line 133, in get return self.__request('GET', url, params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/andrasnagy/Desktop/sensae/code_base/projects/slack-app/.venv/lib/python3.11/site-packages/airtable/airtable.py", line 107, in __request error_type=error_json.get('type', str(r.status_code)), ^^^^^^^^^^^^^^ AttributeError: 'str' object has no attribute 'get'

I did check the type of "at_client", and as expected, it is of type "<class 'airtable.airtable.Airtable'>". Anyone has seen this issue already?
