Bug: aws_lambda_powertools.utilities.parser.pydantic does not exist anymore while mentioned in the documentation

[VladimirSvoboda]

Expected Behaviour

Contrarily to what is stated in the documentation, since the version 3 (and more precisely the pull request #4502) , it is not possible anymore to import any Pydantic module/function through aws_lambda_powertools.utilities.parser.pydantic.

In my case, I would like to be able to import the decorator @field_serializer

Current Behaviour

python -c "from aws_lambda_powertools.utilities.parser.pydantic import field_serializer"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'aws_lambda_powertools.utilities.parser.pydantic'

Code snippet

python3 -m venv venv source venv/bin/activate pip install aws-lambda-powertools[all]==3.1.0 python -c "from aws_lambda_powertools.utilities.parser.pydantic import field_serializer"

Possible Solution

1. Restore the file aws_lambda_powertools/utilities/parser/pydantic.py removed in #4502
2. Correct the documentation

Steps to Reproduce

Execute the following code snippet

python3 -m venv venv
source venv/bin/activate
pip install aws-lambda-powertools[all]==3.1.0
python -c "from aws_lambda_powertools.utilities.parser.pydantic import field_serializer"
