When creating a uac object via the API, 'sqn' is not mandatory, resulting in a 'null' value in the database if ommitted:
Subsequently when getting AIR comes in, the following exception occurs as there is no 'None' check before casting:
[08/21/2024 18:00:16] [ERROR] Traceback (most recent call last):
File "/pyhss/lib/diameter.py", line 1818, in Answer_16777251_318
vector_dict = self.database.Get_Vectors_AuC(subscriber_details['auc_id'], "air", plmn=plmn)
File "/pyhss/lib/database.py", line 1572, in Get_Vectors_AuC
rand, xres, autn, kasme = S6a_crypt.generate_eutran_vector(key_data['ki'], key_data['opc'], key_data['amf'], key_data['sqn'], kwargs['plmn'])
File "/pyhss/lib/S6a_crypt.py", line 37, in generate_eutran_vector
sqn = int(sqn)
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
I'd also expect an error response on the AIR when the TypeError is thrown but there is no response to the diameter request seen.
Alternative would be to do a 'null' check before casting to int.
