Type Error on Python 3.11

When running the first example, I get the following error:

Traceback (most recent call last): File "C:\code\qoria\appstore-client\main.py", line 14, in client = AppStoreServerAPIClient(private_key, key_id, issuer_id, bundle_id, environment) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\code\qoria\appstore-client\venv\Lib\site-packages\appstoreserverlibrary\api_client.py", line 97, in init self._signing_key = serialization.load_pem_private_key(signing_key, password=None, backend=default_backend()) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\code\qoria\appstore-client\venv\Lib\site-packages\cryptography\hazmat\primitives\serialization\base.py", line 25, in load_pem_private_key return ossl.load_pem_private_key( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\code\qoria\appstore-client\venv\Lib\site-packages\cryptography\hazmat\backends\openssl\backend.py", line 747, in load_pem_private_key return self._load_key( ^^^^^^^^^^^^^^^ File "C:\code\qoria\appstore-client\venv\Lib\site-packages\cryptography\hazmat\backends\openssl\backend.py", line 897, in _load_key mem_bio = self._bytes_to_bio(data) ^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\code\qoria\appstore-client\venv\Lib\site-packages\cryptography\hazmat\backends\openssl\backend.py", line 479, in _bytes_to_bio data_ptr = self._ffi.from_buffer(data) ^^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: from_buffer() cannot return the address of a unicode object

What is the datatype of your private_key variable? Is it bytes as specified in the typing, and not a string?

[asifshiraz]

I'm just doing

key_file = open("./SubscriptionKey_S84FG2P8CL.p8", "r") private_key = key_file.read()

[asifshiraz]

Okay.. setting it to rb like key_file = open("./SubscriptionKey_S84FG2P8CL.p8", "rb")` works. Is this the right approach?

[alexanderjordanbaker]

Yes, this is the expected approach
