Bug ::: folder validators ::: Missing return from field_validator (-s)

[AlesCUMSI]

Hi!

I validators folder, there are bugs in severak validators.
They all follow the same principle:
@field_validator('treatments')
@classmethod
def check_treatments(cls, v: list) -> list:
for treatment in v:
Treatment(**treatment)

Field validator MUST return v (it is correct in some part of code, but not all). Because of this all this fields are set to null by pydantic (it is not an exception, they are just set to null).
