Failing pydantic validation on request_dict

[cadlagtrader]

When running the httpx crawler on v0.3.7
My request_dict
'{"url": "XXXXXX", "unique_key": "YYYYY", "method": "GET", "headers": {}, "query_params": {}, "data": {}, "user_data": {"__crawlee": {"state": "RequestState.ERROR_HANDLER"}}, "retry_count": 1, "no_retry": false, "id": "doOfa0tGsjBwT90"}'

create the exception below when running Request.model_validate(request_dict)

user_data.__crawlee.state
  Input should be 0, 1, 2, 3, 4, 5, 6 or 7 [type=enum, input_value='RequestState.ERROR_HANDLER', input_type=str]

Hello and thank you for your interest in Crawlee! Where does that request_dict come from? The state property is suspicious.

Hello - the request_dict comes from a deserialised request from my crawlee storage. There is a bug in Crawlee enum serialisation/deserialisation through Pydantic (I am using v2.9.2, compatible with crawlee pyproject constraints)

I have modifed test_complex_user_data_serialization to highlight the issue: https://github.com/cadlagtrader/crawlee-python/blob/bug_with_pydantic/tests/unit/storages/test_request_queue.py
