Here, value attribute of both Schema1 and Schema2 has type ValueObj > str | None but Schema1 should be int | None and Schema2 should be str | None.

class ValueObj(RootModel):
    """
    None

    """

    root: str | None


class Schema2(BaseModel):
    """
    Schema2

    """

    model_config = ConfigDict(
        populate_by_name=True,  # Addressing by field name, even if there is an alias.
    )
    value: ValueObj | None = None


class Schema1(BaseModel):
    """
    Schema1

    """

    model_config = ConfigDict(
        populate_by_name=True,  # Addressing by field name, even if there is an alias.
    )
    value: ValueObj | None = None # It should be int | None, instead it is annotated as str | None
