Code Sample, a copy-pastable example

import pandas as pd
import pandera as pa
from pandera.typing import DataFrame, Series

class PanderModel(pa.SchemaModel):
    name: Series[str] = pa.Field(alias="old_name.*", regex=True)

df = pd.DataFrame(
    [{"error_name": 1},]
)

PanderModel.validate(df, lazy=True)

Expected behavior

Raise SchemaErrors
