What went wrong?

Test script I have been using for a while now has started throwing errors related to access list in Ape 0.7.5 and higher.

1. Created an access list using Anvil and eth_createAccessList.
2. Pass that access_list into a contract call with raw calldata

tx = contract(
    data=calldata,
    gas=200_000, 
    max_fee=70_000_000_000,
    max_priority_fee=1,
    value=tx_value,
    nonce=nonce,
    sender=account, 
    access_list=access_list,
)

3. In Ape 0.7.4 and lower, this works perfectly. Now after 0.7.5, it throws an error. The error goes away if I remove the access_list parameter.

Traceback (most recent call last):
  File "/Users/xxx/opt/anaconda3/envs/ape/lib/python3.10/site-packages/eth_pydantic_types/serializers.py", line 3, in <lambda>
    hex_serializer = plain_serializer_function_ser_schema(function=lambda x: x.hex())
AttributeError: 'str' object has no attribute 'hex'

The above exception was the direct cause of the following exception:
