Hi, I believe there is an error with the encode_structured_data function. So I currently have a structured_message that I am trying to encode and generate a signature for:
TypeError: Object of type bytes is not JSON serializable
I then converted the listingsRoot to a hexstring and tried submitting it only to get the following error:
``TypeError: Value oflistingsRoot(0x5057c9046ab5607abbe1a5f31836cbf96f536488060fd6b1b4df375772ab050e) in the structOrderis of the type<class 'str'>`, but expected bytes32 value
I am not sure if this is a bug because it keeps going and I can't seem to encode the structured message.
### Code that produced the error
```python
listings_root_bytes32 = bytes.fromhex('5057c9046ab5607abbe1a5f31836cbf96f536488060fd6b1b4df375772ab050e')

Fill this section in if you know how this could or should be fixed
We recently removed encode_structured_data in favor of encode_typed_data. Docs here. Try giving that a shot instead. If you need further help, feel free to post in our discord, as this is a usage question, not a problem with the library.
